For a force F acting on a rigid body in plane motion, the power P delivered by the force is given by P= F x a, where a is the acceleration of the point on the body to which the force is applied. P= Fa, where a is the acceleration of the point on the body to which the force is applied. O P= F. v, where v is the velocity of the point on the body to which the force is applied. O P= F x v, where v is the velocity of the point on the body to which the force is applied
