A
AccelerationRate of change of velocity. | |
Average velocityTotal displacement divided by total time. | |
C
Change of directionThe event that occurs when velocity passes through zero and changes sign. | |
Changing speedmotion in which an object's speed increases or decreases. | |
Closing speedThe rate at which the separation between approaching objects decreases. | |
Constant speedmotion where speed does not change. | |
Constant velocityMotion with unchanged velocity. | |
D
DecelerationA decrease in speed. | |
DisplacementChange in position, including direction. | |
Distancehow far an object has travelled. | |
