07+Types+of+Energy

-energy can be transformed from one type to another (kinetic energy to potential energy or vice versa) -Or transferred from one place to another
 * __Law of Conservation of Energy__- energy cannot be created or destroyed: it may be transformed from one form into another, but the total amount of energy never changes

__Kinetic Energy__- the energy of motion -(KE=1/2mv^2) -Types are basic motion, wave motion, electrical, and thermal

__Potential Energy__- energy stored and held in readiness, this energy has the potential to do work -(PE=mgh) -Types are gravitational, electrical, and nuclear **




 * The Gravitational Potential Energy that this rollercoaster had at the top of the hill is now being converted into Kinetic Energy, but some of this is heat energy, which heats up the track underneath. **




 * Both the wrecking ball and the taught bow have Potential Energy, the potential to do work. The wrecking ball's Potential Energy will increase with the elevation of the ball, and the bow's potential will increase the further the string is streched. **



**The Newton's Cradle has potential energy when one of the end balls is raised above the rest. Once this ball is released and it collides with the resting balls, the energy is transferred to the ball on the other end. This is a great example of the conservation of energy, because a perfect cradle would never stop. The energy would keep transferring to opposite ends, and only friction stops this from happening.**
