Question

if the frequency of an object in uniform circular motion is doubled​

Answer 1

Answer:

Consider an object in circular motion with linear velocity v.

Let the angular velocity be ω and angular accelaration be α.

Linear velocity v = rω

Also, angular Accelaration α = v2 / r = r2ω2 / r = rω2

Thus, when angular frequency is doubled, the angular acceleration becomes 4 times the original value.
