Question

explain me uniform circular motion in detail...plz its urgent

Answer 1

When a body or object moves in a circle, it is said to be in a circular motion. That is we can say that motion in a circle is a circular motion. When a body or object moves along a circular path, then its direction of motion or direction of speed keeps changing continuously. So, if an athlete moves with a constant speed along a circular path, then the velocity of the athlete will not be constant because velocity is the speed in a specified direction and here the direction of speed changes continuously. Since, the velocity changes with the continuous change in direction, therefore, the motion along a circular path is said to be accelerated.
