Answer:
Acceleration
Step-by-step explanation:
The rate of change of velocity is known as acceleration. Acceleration is the rate of increase/decrease in motion, action or speed
Suppose the initial speed of any object is
and the final speed of any object is
and the object changes this speed in a time period of
seconds, then the mathematical formula for acceleration would be

where, "a" is the acceleration
The unit of acceleration if meter per second square.
