Question

CHOOSE ONE

(a) Two objects are experiencing uniform circular motion (motion in a circular path with constant speed). Object 2's speed is twice as big as object 1's, and the radius of the path followed by object 2 is twice as big as the radius of object 1's path. How do the magnitudes of their accelerations compare?

Because the speed is constant, neither object has an acceleration.

The magnitude of object 1's acceleration is two times larger than the magnitude of object 2's acceleration.

The magnitude of object 1's acceleration is four times larger than the magnitude of object 2's acceleration.

The magnitude of object 2's acceleration is two times larger than the magnitude of object 1's acceleration.

The magnitude of object 2's acceleration is four times larger than the magnitude of object 1's acceleration.

Explanation / Answer

a= v^2/r The magnitude of object 2's acceleration is two times larger than the magnitude of object 1's acceleration.
