Forces 
Newton's Three Laws of Motion
First Law
Second Law
Third Law
Inertia
Objects at rest/motion tend to stay at rest/motion
Force and Acceleration
F = ma
Action and Reaction
For every action, there is an equal and opposite reaction.
F(a) = −F(b)
As water goes out from the bottom, the rocket will fly up.
The force of the rocket is determined by the mass and acceleration.
The rocket will remain in rest unless acted on by a force.
Net Force = Mass x Acceleration
Work and Energy
Work
Energy
W = Fd
Action of an object that displaces an object
Kinetic Energy
Potential Energy
Examples
Pushing a cart 10 m with 10 N of force
Pushing a building 0 m with 20 N of force
Equal to 100 J
SI unit
joule (J)
1 J = 1 N * m
Equal to 0 J
Energy possessed by an object due to its surroundings
Examples
A ball at the top of a hill
An arrow notched in a fully-drawn bow
P.E. = mgh
Mechanical Energy
The sum of Kinetic and Potential Energy
Energy possessed by an object due to its motion
