Newton’s Three Laws of Motion
Force: A Push or Pull
First Law An object in motion will stay in motion or an object at rest will remain at rest unless it is acted on by a net outside force.
Inertia Inertia is the tendency of an object to resist a change in the state of its motion.
Second Law If a net outside force is acting on an object then the object will accelerate at a rate proportional to the net force and in the direction of the net force.
AP 2nd Law Equation
Mass vs. Weight
Every force is accompanied by an equal and opposite force. Third Law Every force is accompanied by an equal and opposite force.
Third Law Pairs Do Not Cancel Although equal and opposite, third law pair forces do not cancel each other out. This is because each force acts on a different object.
