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 energy also 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. Mechanical 2. Gravitational 3. Electrical 4. Nuclear 5. Chemical List five examples of kinetic energy. 1. Motion 2. Sound 3. Thermal 4. Radiant 5.

What is energy? - energy is the ability of objects to do work - energy comes in 2 catagories: potential and kinetic - potintial energy is enegy stored in an object - kinetic energy is moving energy - types of energies are; mechenical, thermal (heat) , light , sound , chemical , eletrical , wind , hydro , nucler and gravitational energy

Wind energy - windmills are use to pump water - wind is relly powerful at time,it can destroy buildings. - windmills now dont look the same as last time, they are all connected to power generators - wind dosent produce a LOT of energy - wind turbines are used to turn wing into electricity - wind is a renewable source of energy

renewable and non-renewable energy -renewable energyis energy that comes from natural resources that can be reproduced -non-renewable energy, however, is the opposite.it comes from natural resources that cant be reproduced. -examples of RE* and NRE**....... (*renewable energy** non-renewable energy) Coal (NRE)- coal comes from burnt pieces of wood .the heat emmited is then turned into eletricity (q(^o^)p) Nuclear (NRE)- nuclear energy are in atom bombs. when realeased it produces light and heat energy (i think) Solar energy (RE)- solar energy is from the sun and without the sun we would die (x.x) Biomass energy(RE)- biomass energy comes from plants and animals (>.0) Wind energy(RE)- wind energy is turn into energy by wind turbines(=P) Hydro energy(RE)- hydro energy comes from generators from a dam (=O i think XP)

Solar Energy - Solar energy comes from the sun - it powers less than 0.1% of our heating and transport -it is now possible to meet all out needs with energy from direct sunlight

Hydroelectricity -it is made by water(even though it is dangerous to mix water and electricity) -it is clean -it dosent produce green house gases -it still hurts the enviroment because water turbines are made out of wood

Geothermal energy -comes from the greek word'geothermal' meaning earth heat. -it is heat within the earth -steam and hot water from the earth is used to power buildings it is renewable energy because the heat from the earth continously comes out of the earth it is generated in the earths core -it is HOTTER than the sun surface!!!!!
