Question

define the centripetal force with example​

Answer 1

Answer:

A force acting on a moving body at an angle to the direction of motion, tending to make the body follow a circular or curved path. The force of gravity acting on a satellite in orbit is an example of a centripetal force; the friction of the tires of a car making a turn similarly provides centripetal force on the car.

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.
