Kinetic and potential energy:
Energy can exist in of 2 main forms. Kinetic energy is the kind of energy you probably think of right away when you imagine the energy. A person running, a car moving down , a speeding aircraft, a chamber of the superheated gas-all these things are visible manifestations of the kinetic energy, or energy in action. The dissipation of electrical power, over the time, is the form of kinetic energy too.
Potential energy is not as brightly apparent. When you raise the block of concrete into air, you are creating potential energy. You remember the units called as foot pounds, the best way to measure such energy, from school physics classes. If you raise a 1 pound weight a foot, it gains 1 foot pound of potential energy. If you raise it 100 feet, it gains 100 foot pounds. If you increase a 100-pound weight 100 feet, it will gain 100× 100, or 10,000, foot pounds of potential energy. This energy becomes evident if you happen to drop a 100-pound weight from a tenth-story window.
