Question

Formula for centripetal force

Answer 1

centripetal force = mv^2/r
or v= wr

centripetal force= mw^2r

Answer 2

Definition of centripetal force. : the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation a string on the end of which a stone is whirled about exerts centripetal force on the stone — compare centrifugal force.

Fc = mv2/r, where Fc = centrifugal force, m = mass, v = speed, and r = radius. An object traveling in a circle behaves as if it is experiencing an outward force. This force is known as the centrifugal force. The equation above shows that the force depends on v-squared over r.

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.
