Centripetal Force
The force needed to bend normally straight path of particle into circular path is called centripetal
force.It is denoted by Fc.
Centripetal force formula
Centripetal force formula
It is also known as inward force or center seeking force.
Explanation
Consider a ball whirled in a horizontal circle as figure.If the snapped then ball will not continuous
to move in circle. If it was at any point then it will follow the path along tangent to the circle.
it means some force is needed to keep the body moving in a circular path.This force is called centripetal force.It always directed toward s the center of the circle.
Examples of centripetal force
(1) A planet moving around the sun.
(2) Motion of nuclear particles.
Explanation
If a body moves in a circle with constant speed the magnitude of velocity remains (same) constant but its direction changes continuously.Due to this change in velocity the body must have an acceleration directed towards the center of circle.such acceleration is called centripetal acceleration.

Define centripetal acceleration
The instantaneous acceleration of an body travelling with inform speed in a circle is directed toward the center of the circle and called centripetal acceleration.Explanation
