=﻿Energy: Forms and Changes= Basic Ch. 5 vocab review: [] // 5-1 Nature of Energy media type="custom" key="7626349" // Brain pop video about different forms of energy. ** 1. Energy is the ability to do work. **

** 2. Energy appears in many forms: (list them) **

** 1.Mechanical Energy ** ** 2. Chemical energy ** ** 3. Nuclear Energy ** ** 4. Heat Energy ** ** 5. Electromagnetic Energy **

// ** 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. **

__ ** Interactive games: ** __ ** Click Download to Play Energy Skate Park. Make your own skating track and see what happens to potential and kinetic energy as you change the track. ** ** [] **

** This game allows you to build a roller coaster, then you can try it out viewing from above OR like you are on the roller coaster! Lots of fun! Must have shockwave on your computer. ** []

** K.E. = (__mass x velocity X velocity__ ) ** ** 2 ** ** 2 . GPE - Weight X height ** ** 3. Energy that has due to its shape or position is called potential energy. ** ** 4. 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. **

// ** 5-4 Conservation of Energy ** // = ** The Law of Conservation of Energy states that energy can neither be created nor destroyed ** by ordinary means. =

=// ** 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. =
