CHAPTER 2 ENERGY
1. Visible light is an example of
Electromagnetic energy
2. Change from one energy form to
another is
Energy transformation
3. Energy stored in the nucleus of an
atom is
Nuclear energy
4. Rate at which energy is transferred
is
Power
5. Energy is measured in units called
Joules
6. An example of something that stores
chemical energy is
A match
7. The law of conservation of energy
states that when one form of energy is
transformed to another
No energy is destroyed in the process
8. Potential energy that depends on
height is
Gravitational potential energy
9. When you rub your hands together
friction transforms
Mechanical energy to thermal energy
10. A spinning turbine has this type of
energy
Mechanical
11. Moving water can be used to
produce electricity because
Energy can be transformed into other
forms
12. The ability to do work or cause
change is
Energy
13. You can calculate an object’s
mechanical energy by
Adding its potential and kinetic
energies
14. Potential energy is
Stored energy
15. When natural gas is used to heat
water the energy transformation is
Chemical energy to thermal energy
16. An example of kinetic energy is
A rolling bowling ball
17. Energy associated with motion is
Kinetic energy
18. Energy associated with motion and
position is
Mechanical energy
19. If an object has mechanical energy
it can work on another object.
20. Electromagnetic energy travels in
the form of waves.
21. If velocity of an object doubles its
kinetic energy is multiplied by 4.
22. Work is the transfer of energy
from one object to another.
23. A baseball flying through the air
has kinetic energy.
24. Water running over a waterfall is
potential energy converted to kinetic
energy.
25. A truck has greater kinetic energy
than a small car when going the same
speed because the truck has greater
mass.
