energy
the energy of an object that is due to the object’s motion
kinetic energy
the energy that an object has because of the position, shape, or condition of the object
potential energy
the amount of work an object can do because of the object’s kinetic and potential energy
mechanical energy
a change from one form of energy to another
energy conversion
a force that opposes motion between two surfaces that are in contact
friction
the law that states energy cannot be created or destroyed but can be changed from one form to another
law of conservation of energy
a resource that forms at a rate that is much slower than the rate at which it is consumed
