Transcript Transfer of Energy from one type to another

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.
