slide 1Physics 1401 - L 1 Frank Sciulli
Introductory Physics Courses Designed for Engineering and Science Students
Three different introductory sequences for people with differing preparations, interests, and goals 1400 sequence: emphasizes basics, connections in the
world, and college level physics problem solving 1600 sequence: + more abstract and theoretical; approach
more mathematical; order of topics slightly different 2800 sequence: the three semesters of the 1600 sequence
in two semesters; specifically for students with advanced placement in mathematics and strong background in physics
All courses incorporate calculus at early stage You are now in Physics 1401(1) … if you are well
prepared in Physics, you are probably in the wrong course

1400 Sequence
Three semester sequence (no labs included) 1401-Mechanics and Thermodynamics 1402-Electricity/Magnetism and Optics 1403-Wave motion and Quantum Mechanics
Each is worth 3.0 points Recommended median grade at B-B+
interface Separate Lab courses (when appropriate)
If 1401-02 only, take 1493 in 3rd semester If all 3 semesters, take 1494 in 4th semester
Emphasizes basics, connections in the world, and college level physics problem solving

Text and Topics
Text is Halliday, Resnick, Walker;"Fundamentals of Physics", 6th ed.(with metromedia CD)Chapters 1-15, 19-21 Mechanics: includes linear motion,
forces, energy, rotations, thermodynamics
Note that chapters 16 – 18 are not covered this semester. These include topics on harmonic motion,
waves, … These topics are part of the third
semester (1403) in the sequence

Mechanics of this Course
No handouts All information transmitted on the web!
Grades (I hate them, but …responsibility to be FAIR!) … detailed policy at website you MUST be able to do problems in exams homework, though only a small component of the final
grade in itself, is an ESSENTIAL tool to assure yourself you know the concepts and how to do problems.
College course: assume all are mature adults Check out the home page and links – all
information that I thought useful is written there … http://www.nevis.columbia.edu/~sciulli

History (people oriented)
13 109 BCE Universe started
5 109 BCE Solar system & Earth formed
2 - 1 106 BCE Man precursors with small brains
105 BCE Homo Sapiens with BI G brains
104 BCE Writing (for business)
1000 BCE Bible written down
400 BCE - 400 Greeks, Romans … ideas … many wrong
1400- 1650 DaVinci, Brahe, Copernicus, Galileo
1650- 1900 Newton, … - - Classical Mechanics
1750- 1900 Franklin,…Maxwell - - Electricity&Mag
1900- "Modern" Physics

Mathematics
x=x0+vtEvery
formula carries a concept!
Read them that wayThe math (algebra,
trigonometry, calculus) are tools to
ends!
slide 11Physics 1401 - L 1 Frank Sciulli
Immediate Future
I assume you know (reviewed in text) algebra and trigonometry well!! vector familiarity (review elementals as we go.) calculus simultaneously (know fundamentals!.)
All assignments and due dates are posted. See website.
Chapter 1 (Measurement, numbers, ...) should be a review of what you know. Read it and make sure.
Chapters 2 (1D motion) and 3 (vectors) also should be largely review.
I will go quickly through first few chapters (so we have time to get through the topics programmed for the semester).

Simple problem (like sample 1 – 4)
Earth spherical? Measure radius!1. Mark lake level at location of
ship and place meter stick on ship side
2. Go to lake shore (d = 4.4km) and sight along lake; find that sighting is on ship side at h = 2.0m.
3. What is the radius, R, of the earth?
Eratosthenes (300 BCE) measured radius of the Earth to 5% using geometry, angle
between Aswan and Alexandria.

In the Beginning
Chapter 1: Units, Dimensions, powers of ten, idea of mass. Should be mostly a review. Make sure you can do the problems in the text. (None assigned.)
Chapter 2: Position, velocity, acceleration in one-dimension (1D). Should also be largely a review. Some discussion here. Problems assigned.
Chapter 3: Vectors -- essential for discussion of more than 1D. We will discuss.
Next lecture, review chapters 2 & 3. Read them and start on assigned homework problems soon.
Finish the day with a pretty description of
the scales of physics … Phillip Morrison
