INTRODUCTIONThis Teacher’s Guide provides information to help you get the most out of Newton’s Laws of Motion. The con-tents in this guide will allow you to prepare your students before using the program and to present follow-upactivities to reinforce the program’s key learning points.

Isaac Newton’s three laws of motion are clearly described, using animation and video to illustrate each law atwork. This video introduction to Newton’s laws combines creative animation with concise narration and a touchof humor. The program is designed to help viewers develop a basic understanding of each law and how it worksin the real world. A number of key physical science terms are introduced and defined: motion, inertia, friction,force, mass, acceleration, and resistance. There’s also a brief introduction to Isaac Newton and his contributionsto our understanding of motion.

LEARNING OBJECTIVESAfter viewing the program, students will:l Develop a basic knowledge of the life of Isaac Newton.

l Grasp the importance of Newton’s contributions to our understanding of motion today.

l Identify and use key vocabulary words related to Newton’s three laws of motion.

l Explain, in basic terms, each of Newton’s three laws of motion.

EDUCATIONAL STANDARDSNational StandardsThis program correlates with the National Science Education Standards from the National Academy of Sciencesand the Project 2061 Benchmarks for Science Literacy by the American Association for the Advancement ofScience. The content has been aligned with the following educational standards and benchmarks from theseorganizations.

l Understand Earth in the solar system.

l Understand energy in the Earth system.

l Understand the history of science.

l Understand historical perspectives.

l Understand the nature of scientific knowledge.

l Understand science as a human endeavor.

l Understand interactions of energy and matter.

l Understand motions and forces.

l Understand transfer of energy.

l Understandings about science and technology.

l Understandings about scientific inquiry.

l Understand science and technology in society.

l Understand change, constancy, and measurement.

l Understand evidence, models, and explanation.

l Understand that no matter who does science and mathematics or invents things, or when or where they do it,the knowledge and technology that result can eventually become available to everyone in the world.

l Understand that a system may stay the same because nothing is happening, or because things are happeningbut exactly counterbalance one another.

l Understand that symbolic equations can be used to summarize how the quantity of something changes overtime or in response to other changes.

l Understand that graphs and equations are useful (and often equivalent) ways for depicting and analyzing patterns of change.

l Understand that in many physical, biological, and social systems, changes in one direction tend to produceopposing (but somewhat delayed) influences, leading to repetitive cycles of behavior.

l Understand that the motion of an object is always judged with respect to some other object or point and sothe idea of absolute motion or rest is misleading.

l Understand that people perceive that the earth is large and stationary and that all other objects in the skyorbit around it. That perception was the basis for theories of how the universe is organized that prevailed forover 2,000 years.

l Understand that telescopes reveal that there are many more stars in the night sky than are evident to theunaided eye, that the surface of the moon has many craters and mountains, the sun has dark spots, andJupiter and some other planets have their own moons.

l Understand that Ptolemy, an Egyptian astronomer living in the second century A.D., devised a powerful math-ematical model of the universe based on constant motion in perfect circles, and circles on circles. With thismodel, he was able to predict the motions of the sun, moon, and stars, and even of the irregular “wanderingstars” now called planets.

l Understand that in the 16th century, a Polish astronomer named Copernicus suggested that all those samemotions could be explained by imagining that Earth was turning around once a day and orbiting around thesun once a year. This explanation was rejected by nearly everyone because it violated common sense andrequired the universe to be unbelievably large. Worse, it flew in the face of the belief, universally held at thetime, that Earth was at the center of the universe.

l Understand that Johannes Kepler, a German astronomer who lived at about the same time as Galileo, showedmathematically that Copernicus’ idea of a sun-centered system worked well if uniform circular motion wasreplaced with uneven (but predictable) motion along off-center ellipses.

l Understand that using the newly invented telescope to study the sky, Galileo made many discoveries that supported the ideas of Copernicus. It was Galileo who found the moons of Jupiter, sunspots, craters andmountains on the moon, and many more stars than were visible to the unaided eye.

l Understand that writing in Italian rather than in Latin (the language of scholars at the time), Galileo presentedarguments for and against the two main views of the universe in a way that favored the newer view. Thatbrought the issue to the educated people of the time and created political, religious, and scientific controversy.

l Understand that Isaac Newton created a unified view of force and motion in which motion everywhere in theuniverse can be explained by the same few rules. His mathematical analysis of gravitational force and motionshowed that planetary orbits had to be the very ellipses that Kepler had proposed two generations earlier.

l Understand that Newton’s system was based on the concepts of mass, force, and acceleration, his three lawsof motion relating them, and a physical law stating that the force of gravity between any two objects in theuniverse depends only upon their masses and the distance between them.

l Understand that for several centuries, Newton’s science was accepted without major changes because itexplained so many different phenomena, could be used to predict many physical events (such as the appear-ance of Halley’s Comet), was mathematically sound, and had many practical applications.

l Understand that although overtaken in the 20th century by Einstein’s relativity theory, Newton’s ideas persistand are widely used. Moreover, his influence has extended far beyond physics and astronomy, serving as a model for other sciences and even raising philosophical questions about free will and the organization of social systems.

l Understand that new ideas in science sometimes spring from unexpected findings, and they usually lead tonew investigations.

l Understand that scientists assume that the universe is a vast single system in which the basic rules are thesame everywhere. The rules may range from very simple to extremely complex, but scientists operate on the belief that the rules can be discovered by careful, systematic study.

l Understand that some scientific knowledge is very old and yet is still applicable today.

l Understand that important contributions to the advancement of science, mathematics, and technology havebeen made by different kinds of people, in different cultures, at different times.

l Understand that modern science is based on traditions of thought that came together in Europe about 500years ago. People from all cultures now contribute to that tradition.

PROGRAM OVERVIEW Newton’s Laws of Motion is a concise video introduction to Newton’s laws, combining creative animation withconcise narration and a touch of humor. The program is designed to help viewers develop a basic understandingof each law and how it works in the real world. A number of key physical science terms are introduced anddefined: motion, inertia, friction, force, mass, acceleration, and resistance. There’s also a brief introduction toIsaac Newton and his contributions to the understanding of motion.

MAIN TOPICSTopic 1: Overview of Newton’s Contributions to ScienceThis section provides a basic introduction to Newton’s laws of motion, as well as his early life and interests.

Topic 2: Newton’s First Law of MotionGalileo’s revolutionary experiments with motion and inertia are observed as the viewer listens in on a reenact-ment of a conversation in his studio. Force, friction, and motion are explained, and the differences in their activity on Earth and in space are examined using easy-to-understand examples.

Topic 3: Newton’s Second Law of MotionNewton’s second law of motion and the relationships between force, mass, acceleration, and the movement ofdifferent objects are explained. Modern-day examples make this concept easy for students to grasp. 4

Topic 4: Newton’s Third Law of MotionNewton’s third law of motion is presented in simple language, and with interesting examples. The easy-to-remember visual examples will help viewers to remember that for every action there is an equal and oppositereaction.

FAST FACTSl Although Aristotle is considered to be one of the greatest thinkers in history, his use of intuitive reasoning

misled him when examining the motion of objects. He did not believe in confirming theories through experiments when a theory seemed logical.

l Until the Middle Ages scientific thought held that Earth was the center of the universe, and that it was stationary.

l Aristotle taught his pupils that heavy objects naturally existed on the ground, and that the reason the heavenlybodies did not fall from the sky was because they were made up of a substance called ether, which waslighter than Earth.

l Early Celtic people believed that heavenly bodies were not lighter than Earth and therefore would somedayfall out of the sky.

l Galileo was one of the first scientists to study the Moon and the stars with a telescope. His experiments laidthe groundwork for Isaac Newton to develop his three laws.

l Motion was separated into its horizontal and vertical components by Galileo, which helped him to explain whyEarth and other planets revolve around the Sun. This radical new perspective caused Galileo to be considereda heretic by the Church.

l Galileo died in 1642, the year that Isaac Newton was born. His experiments laid the groundwork for Newton todevelop his Universal Law of Gravitation.

l In 1664, Isaac Newton proved that the orbits of the Moon and other planets were elliptical.

l Isaac Newton developed a theory of colors to explain that sunlight is a blend of different rays of color, andthat reflections and refractions cause colors to appear by separating the blend into its parts. He demonstratedthis by passing a beam of light through a prism to split the individual rays of color.

l Newton compared his scientific contribution to that of a young boy picking up a few shiny seashells on theshore of a vast ocean.

VOCABULARY TERMSacceleration:The rate of change in an object’s velocity over time.

atmosphere: All the air surrounding Earth.

force: An invisible push or pull on an object.

friction:The resistance to motion between things that touch.

inertia:The tendency for an object to remain at rest or continue in a fixed direction unless affected by an out-side force.

mass:The measure of an object’s inertia.

motion: Movement.

natural philosopher:The term for a scientist in the 1600’s.

Newton’s First Law of Motion (Law of Inertia): An object at rest tends to stay at rest, and an object inmotion tends to stay in motion with the same speed and in the same direction, unless acted upon by an outsideforce.

Newton’s Second Law of Motion:The acceleration of an object as produced by a net force is directly propor-tional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to themass of the object.

Newton’s Third Law of Motion: For every action, there is an equal and opposite reaction.

reflection: Light, heat, or sound that has been thrown back or deflected.

refraction:The bending of a wave of light, heat, or sound.

resistance: A force that tends to oppose or retard motion.

ASSESSMENT QUESTIONSQ: Sam went roller-skating at the local rink last week. Because he is a relatively new skater, he lost control, stum-

bled, and crashed into the wall at full speed. When he stood up, he noticed that the wooden railing had asmall dent where his head must have hit. Luckily, he was wearing a helmet, which also had a dent. Which oneof Newton’s three laws of motion explains the damage to the helmet and railing?

(a) Newton’s first law(b) Newton’s second law(c) Newton’s third law(d) None of them. It was just an accident.

A: (c)Feedback: Newton’s third law states that for every action there is an equal and opposite reaction, whichexplains why Sam’s helmet and the wall were both damaged.Q: In the 1600’s, scientists were called _____________.A: natural philosophersFeedback: Natural philosophers studied facts and made observations to find “truth.”

Q: Newton’s first law (the law of inertia) can be seen most dramatically in space because ____________.(a) there is no gravity in space(b) planets and objects are in orbit(c) the heat from the sun increases the speed of an object(d) all of the above

A: (b) Feedback: Gravity exists everywhere, at varying degrees, even in space. Objects in orbit display a perfect balance between inertia (forward movement) and gravity (vertical movement), causing a constant “tug-of-war”which results in an elliptical orbit. On Earth, inertia is weaker than gravitational force, so objects will eventuallyslow and come to a stop.

Q: Newton studied under Galileo, and upon Galileo’s death, built upon his work. (True or False)

A: FalseFeedback: Although he did build upon the work of Galileo, Newton never met Galileo. Newton was born in1642, the same year that Galileo died.

Q: Which object will require the most force to move?(a) A beach ball(b) A baseball(c) A bowling ball(d) A soccer ball

A: (c) Feedback: A bowling ball is the heaviest ball—it has the greatest mass—and therefore will require the greatestamount of force to overcome its inertia, or cause it to move.

Q: Name two things that will create friction to stop an object in motion.Answer/Feedback: Friction is caused by any two things that touch; such things may include atmosphere (air,wind), water, ground, carpet.

Q: Which of the following items have mass?(a) A feather(b) A person(c) Water(d) All of the above

A: (d)Feedback: All objects have mass.

Q: What is the definition of “force”?A: Force is an invisible push or pull on an object Feedback: Force is an integral part of Newton’s second law of motion, which states “The acceleration of anobject as produced by a net force is directly proportional to the magnitude of the net force, in the same directionas the net force, and inversely proportional to the mass of the object.”

Forces and MotionIn New York City, there are many ways to travel. Of course, it’s a lot easier if you’re a bird. Using the Big Apple asa living laboratory, this program addresses speed and distance using a pigeon, a taxi, and a tour boat. Additionalsituations such as the deployment of a Mars rover, a zero-G flight in NASA’s Weightless Wonder, a walk on a conveyor belt and a cruising aircraft carrier, and juggling on the Earth and around the Solar System provideopportunities to study the mechanics of velocity and acceleration as well as contact forces and forces that act ata distance. Vector algebra is demonstrated throughout. A viewable/printable instructor’s guide is available online.A Films for the Humanities & Sciences Production. A part of the series Physics in Action.

Planets, Stars, and GalaxiesBeginning with the history of astronomy (Ptolemy, Copernicus, Giordano Bruno, Galileo), this program considersthe mathematics of motion (velocity, acceleration); gravity (Kepler’s discoveries, Newton’s laws, center of gravity,astronomical units); the properties of stars (parallax, flux, luminosity, color, Hertzsprung-Russell diagram); relativity (Einstein’s theories, speed of light, space-time); and the large-scale structure of the universe (Big Bang,Cosmological Principle, Hubble’s law). Humankind has come a long way in our understanding of the cosmos—but we’re still only scratching the surface of astrophysics, with discoveries of incalculable value still waiting to be made.

Principles and Laws of MotionTo study and understand the motion of objects in space, students need to build a foundation of knowledge in awide variety of physical science phenomena. This program demonstrates typical mechanics situations commonto many physics courses, such as circular motion, projectile motion, straight line motion, and inclined planemotion. Describing these motions in terms of forces and energy transfers, the video examines the topic ofmotion using a series of large-scale, real-world examples. In the process, it deals with issues such as uncon-trolled variables of nonuniform friction and subsequent energy loss. Each topic is illustrated through detailedanalysis, discussion, and visuals.
