The hand of the clock performs periodic motion. This is because the motion will repeat after a given interval of time. The motion of the hand of the clock can also be called as rotatory motion. The hand rotates about a fixed point at one end of itself.
What is needed for uniform circular motion?
Uniform circular motion can be described as the motion of an object in a circle at a constant speed. … Circular motion requires a net inward or “centripetal” force. Without a net centripetal force, an object cannot travel in circular motion.
What changes uniform circular motion?
Velocity of the body changes continuously in uniform circular motion. It is continually shifting its direction when an object travels around a circle. Accelerating objects – either the velocity (i.e. the magnitude of the velocity vector) or the direction are objects which change their velocity.
