What Is Circular Motion
Circular Motion When a body moves in such a way that its distance from a fixed point always remains constant, then its motion is said to be the circular motion.Uniform circular motion: If the radius vector sweeps out equal angles in equal times, then its motion is said to be uniform circular motion.In uniform circular motion speed remains constant. Linear velocity, … [Read more...] about What Is Circular Motion
