Question

How does an object’s motion change as a result of centripetal acceleration?

Answer 1

D the last one or as down below

The direction changes but not the speed.

took the test and this is the correct answer as of on the class Physics A

Answer 2

Explanation :

When an object moves in a circular track, its speed remains constant while direction changes continuously.

Acceleration is basically the rate of change of velocity per unit time. The centripetal acceleration is given by :

`a_c=(v^2)/(r)`

v is the speed of the object.

r is the radius of the circular path.

So, we have concluded that in a circular motion the direction changes but the speed is constant.
