Question

Derive the formula for power delivered to a body Prove that
instantaneous power delivered to a body is given by the product of
force and velocity of the body

Dear Student,Power is defined as the work done in unit time or the energy used in unit time
Hence,Power=Work time=Wtor,Power=Energytime=EtWe take,P=Wt
(1)Work done,w=F×swhere,F→Applied forces→Displacement of the bodyEquation( 1) becomes,P=F×st=F×v     (velocity, v=st)Hence,Power=Force × VelocityRegards
