- We know, acceleration is the change of velocity by time.
- Velocity is the speed of an object which also indicates the direction.
- Hence, acceleration is both dependant upon the speed as well as the direction.
- So, if an object is moving at a constant speed in a changing direction, the acceleration will also change. It will not be zero.
- An example is that of uniform circular motion.
