Acceleration is the time rate of change of velocity. If velocity is constant, then. acceleration is zero. Note: 100 km per h for 10 seconds is a constant speed, but not necessarily a constant. velocity, since we're told nothing about the direction.
Constant acceleration : Acceleration is said to be constant when the rate of change of velocity of an object is constant. In many types of motion, The acceleration is either constant or approximately constant, For example when you drive a car and accelerate it, you accelerate it in almost constant rate.onstant acceleration : Acceleration is said to be constant when the rate of change of velocity of an object is constant.
