what is meant by circular uniform motion? give a relationship between radius speed and time taken to complete one round by a body moving along a circular path
Answers
Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle.
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.
