Test 8 ~ Objective 3

Objective 3:

1. Some of the forms of energy related to changes in matter are chemical energy (because it makes a chemical reaction, which can make a different substance, such as plasma), and thermal energy.

2. A rolling ball has kinetic energy (because it is in motion.)

3. A bowling ball sitting still has potential energy (because it is sitting in place.)

4. Electromagnetic energy is energy of or from radiation.  It can transmit energy in the form of waves from one place to another.  The stuff that it transmits can be in the form of heat, light, or anything else.

5. The energy of electrons moving from one place to another is called electric energy.  An example is this is charging a computer.  The electrons go from a power line, into a wire that connects our school, through the wall and into the power cord, and then finally (when you plug it in) the electrons go into your computer.
