# Relation between momentum andkinetic energy. Note that if a massive particle and a light particle have thesame momentum, the light one will have a lot more kinetic energy. If a light particle and a heavy one have thesame velocity, the heavy one has morekinetic energy
#The work power and energy are interdependent on each other. But this just simply do not means that work is equal to energy did just have their S.I. units same that is J (joules). The power something different from both them it is defined as rate of flow of energy.
#The expression P = F v expresses a relation between the instantaneouspower, the force and the velocity. You don't have to average for it to be true. In your case, the velocity in constant. This implies that the net force is zero
#The SI unit joule is too small toexpress very large quantities of energy. Hence we use a bigger unit calledkilowatt hour (kWh) to express energy. 1 kWh is the amount of energy consumed by an electrical gadget in one hour at the rate of 1000 J/s or 1kW. The commercial unit of energy is B.O.T.
