1. What is energy?
Energy is the ability to do work
2. What is kinetic energy?
Kinetic Energy is the energy in motion
3. What is potential energy?
Potential Energy is the energy at rest or position
4. What are the 11 forms of
energy?
Mechanical, elastic, thermal, chemical, sound, geothermal,
5. Of the 11 forms of
energy, which are forms of
potential energy?
Nuclear, chemical, elastic, magnetic, nuclear
6. Of the 11 forms of
energy, which forms are
kinetic energy?
Mechanical, thermal, geothermal, sound, electric, light
7. What factors affect the
amount of kinetic energy an
object will have?
* mass and velocity
8. What type of energy do
you experience when you
eat a sandwich?
Chemical (all food is stored energy)
9. What are conduction,
convection, and radiation?
Conduction: direct heat transfer (two objects touching)
magnetic, electric, light, gravitational, nuclear
* more mass or more velocity equals more kinetic energy
Convection: heat transfer in liquid or gas
Radiation: heat transfer through space
10. In what direction will
heat flow between two
objects with different
temperatures?
11. What is the Law of
Conservation of Energy?
From Hot to Cold
12. What are mechanical
waves? What energies are
transferred through these
waves?
Mechanical waves: energy that must have a medium to be
13. What are
electromagnetic waves?
Electromagnetic Waves: a medium is not needed for
Provide examples of
electromagnetic waves.
14. On a roller coaster,
where is the position you
would have the most
potential energy? Kinetic
energy?
Energy can not be created or destroyed……..it is never
lost or gained; it just changes from one form to another.
transferred. Examples: Sound, geothermal (earthquake)
transferring of waves.
Examples: light, gamma, x-rays, ultraviolet
Top of the largest hill would be the greatest potential
energy.
Towards the bottom of the hill would be the greatest
kinetic energy.
15. Map out the energy flow
of an electric fan turned to
the “On” position.
Electricmechanicalsound
