Problem 2CQ

Can centripetal acceleration change the speed of circular motion? Explain.

Step-by-Step Solution:
Step 1 of 3

Solution 2CQ

If an object is moving in a uniform circular motion, the acceleration associated with this motion is the centripetal acceleration. Centripetal means the body is accelerated toward the  center of the circle along which it is moving.

In a uniform circular motion, the speed of of the body remains the same along the path. But the velocity of the body changes from one point to another in the path because of the change in direction of its motion. The direction of motion is always tangential at point in a circular path. The acceleration, which is directed toward the center has no component along the direction of velocity. Therefore, centripetal acceleration cannot change the magnitude of velocity or speed of circular motion.
