Question

What is the amount of work done by a force when a body moves in a circular path?

Answer 1

Hint: As when any body moves in a circular path, that means the body is moving on a fixed axis of a circular path. And also in uniform circular motion, the body will finally complete its rotation on its origin.

Complete answer:
The work done on a body moving in a circular path is also zero. This is due to the fact that when a body moves in a circular direction, the centripetal force applies along the radius of the circle, which is perpendicular to the body's motion. As a result, the effort done by the moon as it orbits the earth is also zero.Because the body's force is directed towards the centre of a circular path (the body is acted upon by the centripetal force). While the displacement is always tangent to the circular route, i.e. non-uniform to the force direction.

The motion of a body following a circular path at a constant speed is described by uniform circular motion in physics. The body's distance from the axis of rotation remains constant at all times since it describes circular motion. The body's speed is constant, but its velocity is not: velocity is a vector number that is affected by both the body's speed and its direction of movement. This varying velocity indicates the presence of an acceleration; this centripetal acceleration is constant in magnitude and always oriented towards the rotation axis. A centripetal force, which is also constant in magnitude and directed towards the axis of rotation, causes this acceleration.

Note: When the centripetal force is applied to an item moving in a circle at a constant speed, the force is always directed inward since the object's velocity is tangent to the circle. In the event of uniform circular motion, the centripetal force does 0 Joules of work.
