Forces and Motion #1

a change in velocity over time acceleration
the tendency of a moving object to keep moving in a straight line or of any object to resist a change in motion inertia
the mass of an object multiplied by its velocity. (The more the mass, the more difficult it is to stop.) momentum
the location of an object position
a group of objects from which a position or a motion is measured frame of reference
how fast an object's position changes with time at any given moment speed
the speed and direction of a moving object velocity
the force that pulls objects together gravity
forces that act together on an object without changing its motion balanced force
forces that do not cancel each other out that cause an object to change its motion unbalanced force
a force caused by two objects rubbing against each other friction
any push or pull by one object on another force
a measure of the amount of matter in an object mass
Things at rest stay at rest, and things in motion stay in motion unless acted on by an outside force. Newton's 1st Law of Motion
To move a mass, you need a force. Newton's 2nd Law of Motion
For every action, there is an equal but opposite reaction. Newton's 3rd Law of Motion
