Answer the following with reference to an object moving in a circle at constant speed:
(a) Distinguish between speed and velocity.
(b) Explain why, even though the speed of the object remains unchanged, its velocity is said to be continuously changing.
(c) State why such a motion is described as an accelerated motion and identify the direction of the required net force at any instant.
