Mechanical energy transformations
... When something is able to change its surroundings or itself, it has energy. Energy is the ability to cause change. Without energy nothing would ever change. When work is done energy is transferred. So, energy can also be described as the ability to do work. Because of this, we measure energy in the ...

ENERGY IN MOTION
... When energy is transferred from where it is stored to where it is used, some energy escapes as heat. Power is a measure of how fast you transfer energy. You can lift an object slowly and work at a low power. Lift it quickly and you work at a high power. ...
