Answer:
Acceleration is the rate of change of velocity with time. ... Any change in the velocity of an object results in an acceleration: increasing speed (what people usually mean when they say acceleration), decreasing speed (also called deceleration or retardation ), or changing direction (called centripetal acceleration ). If the velocity of the object increases with time, its acceleration increases. If the velocity of an object decreases with time, its acceleration is negative.
