Why is an object moving at constant speed along a circular path said to be in accelerated motion?
(a) Because its speed increases at each instant
(b) Because it covers equal distances in equal intervals, implying uniform acceleration
(c) Because its velocity changes direction continuously while the magnitude remains constant
(d) Because the centripetal force is balanced by centrifugal force, resulting in net acceleration
