Question

explain circular motion
krp qfho pms

Answer 1

Answer:

The motion is called uniform circular motion when the particle is moving along a circular path possessing a constant speed. During circular motion, the velocity vector changes its direction at each point on the circle.

Answer 2

Answer:

Circular motion is described as a movement of an object while rotating along a circular path. Circular motion can be either uniform or non-uniform. During uniform circular motion the angular rate of rotation and speed will be constant while during non-uniform motion the rate of rotation keeps changing.

Some of the most common examples of circular motion include man-made satellite that revolves around the earth, a rotating ceiling fan, a moving car’s wheel, the blades in a windmill, and gears in gas turbines.

A particle is said to execute circular motion when it moves along the circumference of a circular path. An important aspect of circular motion is that the direction of motion is changing continuously unlike in the case of linear motion. Hence circular motion can also be described in terms of angular variables.

Angular Velocity

It is defined as the rate of change in angular displacement of a particle in a circular motion. It is denoted by ω.

Relation Between Linear Speed(V) And Angular Speed(Ω)

In vector form

v= ω x r
