An acceleration index is a vector quanity, which is defined as the rate at which a defined object changes its velocity.
increase rate in speed of acceleration
That's the definition of 'acceleration'.
Another definition for the word "acceleration" is "the rate of change of velocity per unit of time."
Whenever a velocity changes, by definition you have an acceleration.
By definition acceleration is the change in velocity (speed).
A map index is a guide to what you will see on the map.
acceleration is a change in velocity (speed + direction)
Literally the definition of acceleration.
Acceleration is a change in velocity over a period of time.
Acceleration is when speed increases. Deceleration is when speed decreases.
Gravity acceleration g=GM/r2.
