Power is the rate of doing work. For example one watt of power is one joule of
work being done each second, and one horsepower is 550 foot pounds of work
being done each second.
power is the work divided by time.
power is required to do work and work efficiancy is the ammount of time it takes to do work.
Power = Work/Time Time = Work/Power Work = Power * Time See related links for a power calculator. Insert work and time to calculate power.
Work and energy are very closely related. Power is the rate of using energy or doing work. Energy is measured in Joules. Power is measured in Joules per second or Watts. Power P is the time derivative of Work W, P= dW/dt. Power = Workdone or Energy / Time

They are both related by a transfer function which is time . And w= force x distance or w= distance x time . P= work / time

The rate of expenditure of energy is power. To perform work energy is needed. So rate of doing work is also known as power. Unit of energy and work is one and the same i.e. joule. So unit of power is J/s This is also termed as watt.

Power is energy divided by time. Solving for energy, energy is power multiplied by time. Work is closely related to energy - work is the amount of energy transferred.
