Newton's 1st Law

An object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted on by some force.

Newton's 2nd Law

Force is equal to an object's mass times its acceleration or F=ma

Newton's 3rd Law

For every action there is an equal and opposite reaction

Inertia

A tendency to do nothing or remain unchanged

Force

a push or a pull on an object that can cause it to accelerate (change its speed or direction)

Acceleration

the rate at which an object's velocity (speed and direction) changes over time

Friction

force of resistance an object encounters while moving against another object

Velocity

the speed of something in a given direction.

Air Resistance

a force that opposes the motion of an object moving through the air, slowing it down due to friction with air molecules.
