Problem
An object moves at a constant speed along a horizontal circular path of radius r.
(i) Write an expression for the distance travelled by the object in one complete revolution in terms of r.
(ii) Using the definition of speed, show that the speed v of the object is given by v=T2πr, where T is the time taken for one revolution.
(iii) Even though the speed is constant, the motion is described as accelerated motion. Explain why, referring to the concept of velocity.
