Question

what is meant by uniform circular motion

Answer 1

First, let us look at what circular motion is.
The motion of any object moving in a circular path, is called circular motion.
Now, uniform motion is defined as a motion in which a body moves equal distances in equal intervals of time.
Hence, we can say that uniform motion is a motion in which, a body moves equal distances in equal intervals of time, in a circular path.

Answer 2

Answer:

When a particle moves along a circular path, its direction changes every moment. The speed of the.particles may change or remain constant. If the speed of the particle moving in a circle is same, it is.said to be in uniform circular motion. Since the direction of the particle is changing every moment, its velocity is continuously changing. Thus, the motion of the body along circular path is an example of accelerated motion. This acceleration acts towards the centre of the circle and hence, called centripetal or radial acceleration.
