Answer the following questions related to uniform circular motion:
(i) Explain why an object moving with constant speed in a circular path is said to be accelerating.
(ii) Starting with the definitions of angular speed and frequency, derive an expression relating centripetal acceleration to frequency and radius.
(iii) Without using numerical values, state how the centripetal acceleration of an object changes if its frequency is tripled while the radius of its path is halved. Give reasons for your answer.
