the rate at with electrical energy is changed into other forms of energy is electric power
How fast work happens or how quickly energy is transferred.
Energy is scientifically defined as the ability to do work, and power as the rate at which work is done, or the rate at which work is expended.
In this case, you are not doing work against the force of gravity, but against the force of friction.

The forms of energy that do work is kinetic energy.
Power is the rate of doing work or delivering energy whereas energy is the capacity for doing work.
(physics) the rate of doing work; measured in watts (= joules/second) - See more at: http://www.chacha.com/question/what-is-the-rate-of-doing-work-or-using-energy-(58%26%2345%3B19)#sthash.l6xRuIk4.dpuf
You cannot store power any more than you can store velocity, because it is simply a 'rate' -the rate of doing work. In order to do work you can store potential energy in, for example, the form of water held behind a dam. When the water is allowed to pass through a turbine, that turbine does work by converting this energy into electrical energy.
"Power" is the rate of work, or of energy transfer.
The rate of doing work or using moving energy is known as power. It is measured in watts and represents how quickly energy is transferred or work is done. Power is calculated by dividing the work done by the time taken to do the work.
Power is the rate at which work is done or energy is transferred. It is measured in watts (W) or horsepower (hp).
it requieres speed,strenth,and energy

When a muscle contracts, it performs work. It does this byA)converting chemical energy to mechanical energy.B)converting mechanical energy into heat energy.C)converting mass into energy.D)creating energy.
The term that represents the rate at which work is done is the watt. It is defined as 1 joule per second.
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
The rate of doing work is a measure of how quickly energy is transferred or converted. It is calculated as the amount of work done divided by the time taken to do the work. The unit of power, watts, is commonly used to express this measurement.
