Acceleration
the rate of change of velocity
Average Speed
the total distance traveled divided by the total time of travel
Constant Speed
When an object is moving neither slowing down nor speeding up
Deceleration
A negative acceleration, slowing down
Displacement
The distance and direction of an object’s change in position from the starting point
Distance
Describes how far an object has moved

Inertia

Speed

Motion
When an object has moved/changed locations
Instantaneous Speed
