| A | B |
|---|
| acceleration | rate at which velocity changes in an object |
| balanced force | net force is 0; no motion; sides equal |
| unbalanced force | net force >0; sides are unequal; motion |
| constant speed | time/distance stay the same; |
| inertia | tendency to remain moving or remain at rest |
| Newton's First Law | object stay at rest or stay in motion |
| velocity | speed in a given direction; 20m/s N |
| reference point | place used to compare if an object has moved |
| linear | shows a straight line on a graph |
| non-linear | shows a curved line on a graph |
| deceleration | speed decreases when velocity changes |
| force | push or pull |
| friction | action between 2 touching surfaces |
| gravity | attractive force between 2 objects |
| speed | rate at which an object moves; distance/time |
