Expert Answer:

Dear student
In physics, a change in the direction of velocity also is an acceleration: for rotary motion, the change in direction of velocity results in centripetal (toward the center)acceleration; where as the rate of change of speed is a tangential acceleration.
We hope this clarifies your doubt.
