Energy Transformations

Law of Conservation of Energy Energy is never created or destroyed. The only thing that changes is the form in which energy appears.

Tracking Energy Transformations #1 Chemical  Motion Chemical  Thermal

Changing Forms of Energy In the world around you, energy is transforming continually between one form and another.

Changing Forms of Energy #2 Forest fires as a result of lightning strikes. Electrical -> Thermal

Tracking Energy Transformations Because of friction, the mechanical parts of the bicycle are warmer, too. Thermal energy is almost always produced by an energy transformation. The energy transformations that occur when people exercise, when cars run, when living things grow and even when stars explode, all produce thermal energy.

Potential energy is converted into kinetic energy. #3 A waterfall Gravitational -> Motion

Energy Changes Form Energy changes form, but the total amount of energy in the universe stays the same.

Energy Changes Form #4 -- Car Chemical  Motion Electrical  Sound Electrical  Electromagnetic

Energy Changes Form #5 Electrical  ?

#6 --- Electromagnetic - ? Photosynthesis . #6 --- Electromagnetic - ?
