Teach Astronomy - Types of Energy
http://www.teachastronomy.com/ There are several broad types of energy. Energy is measured in units of calories in the English system or joules in the international system of metric units. One broad category of energy is kinetic energy, or the energy of motion. A second broad category of

Energy, Work & Power (24 of 31) Power, An Explanation
Gives an explanation of what power is in physics. Includes a explanation of horsepower and one worked example. Power is the rate a which work is done. Also stated as how fast work is done. Power is calculated as the amount of work done divided by the time it takes to do the specified amo

Energy Use In Electrical Appliances | Energy | Physics | FuseSchool
Do you ever have arguments at home about leaving appliances on and wasting electricity? In this video we are going to look at measuring energy use, in electrical appliances. The unit of energy is the Joule (J). However, when dealing with electricity, we actually use Watts (W). A Watt is
