Uniform circular motion
Tanusri Gururaj, Academic content writer of Physics at Edumarz
A body moves along a circular path such that the magnitude remains constant but the direction changes at a constant rate.
The body undergoing uniform circular motion has uniform speed but, the velocity keeps changing.
The body’s acceleration acts towards the center, and the velocity is tangential to the circle.
Speed of body undergoing such motion:
v = distance/time
The distance covered by body = circumference of circle = 2πr
Let us assume that a body takes ‘t’ seconds to go once around the circular path, and the radius of the path is r.
Speed = v = 2πr/t
Examples of uniform circular motion-
The motion of the Earth around the Sun
The movement of the hands of any clock
A cyclist’s motion on a circular path
