Energy


 * Kinetic energy is energy of motion. A rubber band flying through the air has kinetic energy. When you are walking or running your body is exhibiting kinetic energy. Potential energy is converted into kinetic energy. Before the yo-yo begins its fall it has stored energy due to its position. At the top it has its maximum potential energy. As it starts to fall the potential energy begins to be changed into kinetic energy. At the bottom its potential energy has been converted into kinetic energy so that it now has its maximum kinetic energy. A waterfall has both potential and kinetic energy. The water at the top of Bridal Veil Falls has stored potential energy. When the water begins to fall, its potential energy is changed into kinetic energy. This change in energyalso happens at Niagara Falls where it is used to provide electricity from the transformation of mechanical and electromagnetic energy to parts of the northeastern United States.

List five examples of potential energy. 1. A parked car 2. A boulder on top of a moutain 3. sleeping 4. table 5. cup List five examples of kinetic energy. 1. car 2. swimming 3. running 4. walking 5. singing ** =Geothermal Energy = ​
 * 10 years ago Paleo Indians used geothermal heat for electricity. Geothermal energy is a renewable source of energy. In the greek language GEO means earth, and THERMAL means heat. **


 * What is energy? **
 * Energy has ability to make objects work. There are 2 types of energy, Potential and Kinetic energy. Potential is stored energy and Kinetic is moving energy. **

Solar energy gets converted through solar panels. Solar energy is a renewable source of energy.** =====

 * Renewable energy can be used again and again, for example: Solar, Wind, Biomass, and more. But Non-renewable energy can be used only once, for example: Coal, nuclear, gas and more. **

Each blade inside of a wind turbine is connected to a generator so each time one of the blades rotates 360 degrees a small amount of energy is produced** ======

Water in motion going through various machinery makes energy. **
