The Increasing and Retardation of Speed

A body is said to be in acceleration if its velocity is changing. As the Velocity is a vector quantity, the change can be in the magnitude or the direction. Thus we can say acceleration is the rate of change of velocity. If the velocity is increasing, we call it acceleration. When the velocity is decreasing, we call it deceleration or retardation. ---------------------------------------------------------------------- Help us make science education more interesting and available to every human being!
