energy
the energy of an object that is due to the object’s motion
kinetic energy
the energy that na 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 energies
mechanical energy

energy conversion
a force that opposes motion between two surfaces that are in contact
friction
the law that states that energy cannot be created or destroyed but can be changed from one form to another
law of conservation of energy
