1.  ___________is the ability to do work or cause change.  ____________is done when a force moves an object through a distance. Work is the transfer of energy. (The object that work is being done on gains energy)  Both energy and work are measured in joules (J).  Example: The wind moving a leaf causes change, therefore, the wind has Energy.

5.  ___________ energy= the energy of motion  ___________ energy= stored energy

6.  The amount of kinetic energy an object has depends on its mass and velocity.  Velocity=how fast an object moves  The more work you do to get an object moving, the more energy you give that object.

8.  A bowling ball would have more kinetic energy than a golf ball when traveling at the same velocity, because you would have to do more work to get the ball moving.  Kinetic energy _____________ when velocity increases.

9.  What is kinetic energy?

10.  This type of energy has the potential to do work.  There are many types: ________________________________________________ ____________________________are the most common.

11.  ____________ potential energy is associated with objects that can be stretched or compressed.  An archer gives potential energy to a bow by pulling it back. This stored energy can send an arrow whistling to its target.

12.  Gravitational potential energy depends on height.  The greater the weight of the object or the greater the height its lifted, the greater its gravitational potential energy.

13.  How could this man increase his gravitational potential energy?

16.  Energy stored in atoms that are about to go through a chemical reaction ◦ Food before you eat it, chemicals before they are mixed, etc.

17.  Chemical  Electrical  Thermal  Sound  Light  Mechanical  Nuclear

18. _____________ energy is energy that is stored in atoms and the bonds between atoms and can be released by various chemical reactions.energy

19.  When you receive a shock from a metal doorknob you experience electrical energy.  ____________________________ produce electricity and they carry electrical energy.  We rely on batteries and power lines to run electrical devices such as radios, lights and computers.

20.  Is the measure of the ____________________ _______________in an object. (atoms and molecules which make up all matter)  These particles have both kinetic and potential energy due to their arrangement and motion.  When thermal energy increases, its particles move faster making it feel warm to the touch. (Ice cream melts when thermal energy increases.)

21.  Energy produced from the __________________ ______________________.  Examples: plucked guitar string, a train horn, someone speaking, etc.

22.  Radiant energy is the ____________________________________________ These waves have electrical properties and magnetic properties.  Examples: light we see each day, ultraviolet radiation, microwaves and infrared radiation.

23.  Energy associated with the _____________ _____ ________________ of an object.  The ______________ of potential and kinetic energy  Examples: frog leaping through the air, swinging a hammer, a spring, bow and arrow, etc.

24.  A type of ____________________ energy.  Stored in the nucleus of an atom and released during nuclear reactions. Nuclear power plants use fission reactions to produce electricity. (nucleus splits apart)  The sun and other stars create energy through nuclear fusion. (nuclei join together)

25.  Are energy and work the same thing?  How are kinetic and potential energy different?  List the forms of energy and give an example of each.
