Energy in the form of motion is called kinetic energy. It can be transformed to other types of energy, such as heat energy or electric energy.
11 There are two basic types ofmechanical energy: Kinetic energy: The energyspecifically associated with anobjectâs motion. A bicycle orskateboard in motionpossesses this form ofmechanical energy. Potential energy: The energyan object has as a result of itsposition or ability to performwork. A stretched rubberband, compressed air, or arock sitting on the top of acliff all have potential energy. FORMS OF ENERGY MECHANICAL ENERGY The energy an object has from its motion or its potential formotion. Many natural systems have forms ofmechanical energy that can be harnessed forpower.
