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

• Hand powered generator chemical electrical Supplier -you or the generator Receiver –light bulb • Driving a car chemical mechanical Supplier –your foot Receiver –gas peddle (bicycle) –foot peddle

• Sun shining on the earth chemical radiant (light) chemical reactions on the sun light and heat in the atmosphere and on the earth Supplier -?

Receiver -?

• Lighter chemical radiant flint and lighter fluid flame

• Making electricity heat mechanical electrical burning oil to power a generator which makes electricity • Heating homes radiant heat solar cells for heating homes

• Solar cars radiant mechanical solar to power cars • People talking chemical sound

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.
