Centrifugal Force and Applications of Horizontal Circular Motion

First we will discuss a basic Horizontal Circular Motion of a Conical Pendulum which is a specific type of circular motion of a simple pendulum. When the bob of a suspended simple pendulum moves in a horizontal uniform circular motion, the string of the bob moves on the surface of cone, such a system is called Conical Pendulum.

Analysis of motion of a Conical Pendulum is

As the circular motion is an accelerated
motion then in the reference frame of an observer moving along the body in
circular motion the body will experience a Pseudo Force due to the normal
acceleration in observer. This Pseudo Force will act in radially outward
direction on body as seen by observer as observers acceleration (centripetal
acceleration) is in radially inward direction. This Pseudo Force on body we
call Centrifugal Force. But on applying Centrifugal Force we need to consider
body to be at rest as it is seen in the frame of an observer who is also moving
in circular motion along with the body.
