	Power:
	Power is defined as the rate of doing work and is given by, The average power is the average amount of work done or energy transferred per unit time. The instantaneous power is then the limiting value of the average power as the time interval Δt approaches zero. When there is a force F acting on a particle so that a displacement of ds takes place, then the work done is given as: Then the power delivered by the particle with velocity v = ds/dt is given as: The unit of power is J/s or watt.
