Physical Science

By Shawn Jeffrey

Atoms

• Atoms are in particles and particles are in everything.

• The three parts in a atom are protons, neutrons, and electrons.

• Everything you breath, touch, and see is made up of Atoms.

• EX: The air you breath, A pencil you hold, And everything you see.

Evaporations

• Evaporations is when a liquid is heated enough to turn it into a gas

• Ex: when a pot of water is on the stove and is boiling this cause evaporation which is the steam in the air

Laws Of Motion

• One… two…three… laws of motion.• Example 2- If you kick a soccer ball the ball

will keep going in one direction until it hits an object and the is ball sent in a different direction.

• Example 3- if you blow up a balloon then let it go the air coming out cause the balloon to fly around

• Example 1-if you shoot an arrow into space it will stay at the same speed until the friction slows it down.

Mechanical Energy

• Mechanical energy is potential energy and kinetic energy combined .

• Potential energy is stored energy.

• Kinetic energy is the energy of motion.

• A car on a ramp that is higher then another car that is farther down the ramp will travel faster

Electricity

• Electricity is a form of energy that’s involves the movement of electric charges.

• In atoms, if there is more proton then

electrons it has a positives charge.

• If it has more electrons then it has a negative charge.

Circuit

• A circuit is a line or route that starts and finishes in the same place

• Ex: A battery, one end is positive the other is negative. If you wrap a wire starting from the positive end and ending at the negative side this will recharge the battery.

Oceanographer

• An oceanographer is a person who studies marine life and ecosystems, ocean circulation, plate tectonics and the geology of the sea floor, and the chemical and physical properties of the ocean.

• It’s compared to physical science because they look to see how much force the waves do.
