Newton's Three Laws of Motion
Objects at rest/motion tend to stay at rest/motion
The rocket will remain in rest unless acted on by a force.
Force and Acceleration
F = ma
The force of the rocket is determined by the mass and acceleration.
Net Force = Mass x Acceleration
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.
Work and Energy
W = Fd
Action of an object that displaces an object
Pushing a cart 10 m with 10 N of force
Equal to 100 J
Pushing a building 0 m with 20 N of force
Equal to 0 J
1 J = 1 N * m
Energy possessed by an object due to its motion
Energy possessed by an object due to its surroundings
A ball at the top of a hill
An arrow notched in a fully-drawn bow
P.E. = mgh
The sum of Kinetic and Potential Energy
