Transfer of Energy from one type to another Rocket -chemical energy held in the rocket’s liquid hydrogen and liquid oxygen tanks used in the engine to power the rocket Chemical energy is converted to kinetic (motion) energy and exhaust gases. ***The chemical energy used in the beginning = (equals) the kinetic energy + the exhaust of the rocket -keeps the rocket going All of the energy is accounted for. The same amount remains, it only changed forms

Conservation of Energy Law Uranium to create a bomb chemical nuclear All of the energy in the universe remains constant (amount) It just changes from one form to another, it is never used up (transfers). Sometimes we can’t reuse the energy because of the form it is now in, but it is still there just useless.
