| A | B |
|---|
| distance traveled divided by the time | speed |
| rate of speed at any given instant | instantaneous speed |
| speed that does not vary/stays the same | constant speed |
| total distance traveled divided by total time | average speed |
| speed and direction of a moving body | velocity |
| change in velocity/ time (speed & direction) | acceleration |
| push or pull exerted by one body on another | force |
| equal in size and opposite in direction | balanced forces |
| changes an object's speed or direction or both | net force |
| in a collision, a person not wearing a seatbelt moves forward because of this | inertia |
| objects at rest, stay at rest unless a net force acts on it | Newton's first law of motion |
| force that opposes motion between 2 surfaces that touch | friction |
| objects drop to the floor because of this force | gravity |
| this will decrease as you move away from the center of the Earth | weight |
| formula for average speed | v = d divided by t |
| formula for acceleration | a = Vf minus Vi divided by t |
| Any change over time | rate |
| gravitational force will be strong or weak depending on this | mass and distance between objects |
