Transfer of Energyfrom 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

• Making electricity

electrical
burning oil to power a generator which makes electricity
• Heating homes
radiant
heat
solar cells for heating homes
Conservation of Energy Law
• Uranium to create a bombchemicalnuclear
• 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.
