12. The motion of a body around a circular path is an example of A.Uniform velocity, variable acceleration B.Uniform speed, uniform velocity C.Uniform speed, variable velocity D.Uniform speed, variable acceleration
Option A Solution: Uniform circular motion occurs when a body moves in a circular path with constant velocity. The acceleration of a body experiencing uniform circular motion is always directed toward the center of the circle (centripetal acceleration or ac = V2 / r where v is the body’s velocity, and r is the radius of the circle). This acceleration is constant in magnitude but changes in direction, so, it is variable at every point of the circular path.
