What is the difference between uniform circular motion and non uniform circular motion? Give examples.
Sr. No U.C.M Non-U.C.M 1. Circular motion with constant angular speed is known as uniform circular motion Circular motion with variable angular speed is called as non-uniform circular motion 2. For U.C.M, α = 0 For non-U.C.M, α≠ 0 3. In U.C.M, work […]
U.C.M is an accelerated motion. Justify this statement.
Definition: In U.C.M, the magnitude of linear velocity (speed) remains constant but the direction of linear velocity goes on changing i.e., linear velocity changes. The […]
