Question

GIVE DERIVATION OF Mv2/r

Answer 1

when a body is moving uniformly along a circular saw the magnitude of its velocity remains constant but is direction changes continuously according to the Newton's first law of motion a body in motion cannot change its direction on its own so A body moving along a circular path is under the influence of a an external force force which can make a body moving along a circular path is the force acting perpendicular to the direction of the velocity and always directed towards a fixed. this force is called the centripetal force its value depends on the mass of the body magnitude of its velocity and radius of its path
centripetal force=mv^2/r
