// ** 5-2 Kinetic and Potential Energy ** //
= 1. Energy that an object has due to its motion is called kinetic energy. = ** 2. Kinetic energy equals one half the product of the mass times the square of the velocity. **

** K.E. = (__mass x velocity X velocity__ ) ** ** 2 ** ** GPE =Weight X height **

** Energy that has due to its shape or position is called __potential energy__. **

** Potential energy that an object has due to its height above the Earth’s **** surface and its weight is called __Gravitational potential energy__. **

=// ** 5-3 Energy Conversions ** //= = 1. Energy can change from one form to another. Changes = ** in the from of energy are called conversions. **

** 2. The most common energy conversions occur between potential ** ** energy and kinetic energy. But all froms of energy can be converted to another form. **

=// ** 5-5 Physics and Energy ** //= = ** 1. Energy is involved in every change or process. ** = = 2. An increase in speed or velocity is accompanied by an increase in kinetic energy. = = 3. An object that has kinetic energy also has momentum. = = 4. A force doing work on an object to change its motion is giving energy to the object. = = 5.Power is the rate at which energy is being used. = = 6. The conservation of work can be understood because energy is conserved. = =Eureka Video= =- Potential Energy= media type="custom" key="7828343" =Kinetic Energy= media type="custom" key="7828359"
