advertisement
 1.
Energy is the ability to do work or cause
change.
 2. You measure energy in joules.
 3. 2 main type of energy is kinetic and
potential.
 4. Mass and velocity
 5. Kinetic energy is the energy an object has
due to its motion.
 6. Potential energy is stored energy as a
result of an object’s position or shape.
 7.
Gravitational potential energy is the
potential energy an object has due to its
height.
 8. Elastic potential energy is the potential
energy an object gains when it is stretched
or compressed. Examples: rubber band and
a bow and arrow
 1.
transferred or converted
 2. Mechanical: energy associated with the
motion of an object.
 Thermal: the total energy of the particles in
a substance or material
 Chemical is the potential energy stored in
the chemical bonds of an object
 Electrical: is the moving electrical charges
that produce electricity and energy
 Electromagnetic: energy that moves in waves
 Nuclear: energy stored in the nucleus of an
atom, released during fission or fusion
 1.
a change from one form of energy to
another.
 2. work gets done
 3.Single transformation- is when energy
changes from one type of energy to another
 Multiple transformation- is when energy goes
through a series of transformations.
 4. Single: electrical
thermal(toaster)
 Multiple: M
C
T
EM (This is process
of striking a match.)
 5.
potential to kinetic
 6. created, destroyed, changes forms
 7. Albert Einstein
 8. a huge amount of energy
 Conduction:
the transfer of heat from one
particle to another by direct contact
 Convection: the transfer of heat as it moves
in currents
 Radiation: the transfer of heat as it moves in
EM waves
 Insulator: stops or resist the flow of heat
 Conductor: allows heat to flow through it
easily
