is one of a number of vital formal quantities in physics that has units of energy. In short, whenever energy is used to make an object move, work is being done on that object.
Hydroelectricity is the most common method of generating electricity.Wateris stored is ahigh damor an artificial or natural lake or reservoir. This water stored in a high place hasgravitational potential energy. Down this source of falling water is a power station equipped with waterturbines. Potent...
(the forces acted upon a moving object by the air -- also defined as drag ) has a tremendous effect on the way a car accelerates, handles and achieves fuel mileage. this where the science of aerodynamics comes into play. aerodynamics is the study of forces and the resulting motion of...
Wavelength is the distance between any point on a wave and the corresponding point on the next wave. Technically, sound isdefinedas a mechanical disturbance traveling through an elastic medium — a material that tends to return to its original condition after being deformed. The medium doesn't ...

Electrical energyon the other hand is defined as the total work done or the total heat generated, but its formula is power times time. It seems difficult to explain one concept without the other. They must be explained at the same time, but you have to start somewhere. ...
How much electricity is in the human body? Scientists agree that the human body, at rest, can produce around 100 watts of power on average. This is enough electricity to power up a light bulb. Some humans have the ability to output over 2,000 watts of power, for instance if sprinting....

and movement in mechanical systems is known as power. Power is defined as the product of a force on an object and the velocity of the object, or the product of a torque on a shaft and the angular velocity of the shaft. The time derivative of work is anoth...
