centripetal force define ​

Answer 1

Credits : Oxford Languages

cen·trip·e·tal force

a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.

Formula

F_c = mv²/r

F_c = centripetal force

m = mass

v = velocity

r = radius

Answer 2

Answer:

Centripetal force is a force acting on particle performing the circular motion, which is a long radius of circle and directed towards the center of circle.

Centripetal force acts at right angles to the tangential velocity of the particle, there is no displacement in the direction of force, hence no work is done by centripetal force.

Explanation:

Centripetal Force

A body moving in a circle of constant radius with a constant speed has a non-zero force acting on it. This force is known as Centripetal force. It is directed towards the center of the circle. Its value is given by the formula:

$F\:=\:\frac{mv^{2} }{R}$

Note: Centripetal force for uniform circular motion is constant in magnitude. However, its direction is continuously changing as it is always directed towards the center of the circle.
