ENERGY

definition: objects ability to do work

for work to be done something must be moved

potiential energy= energy of position, the possibility of energy

work: force applied to an object that causes movement

chemical potiential energy:energy stored in chemicals

nuclear energy= energy stored in an atom

gravitational potential energy= energy based on an objects height

mechanical energy= KE+PE, energy of motion and position

law of conservation of energy= energy is never created or destroyed. energy can be converted/changed to other types of energy
