'Energy that changes from one form to another'

• Energy Transfer

• Energy Transformation

Identify the ways energy can be transferred

• Mechanically

• Electrically

• Via radiation

• Via heating

In a battery, that is a closed circuit the electrons flow from

• Positive to negative

• Negative to positive

• One terminal to the other terminal

• Whichever way, as there is no affect

Electrical resistance is the

• How the electrical current flows

• The direction the current flow

• Opposition of the flow of current

• Gaining of flow from the electrical current

 $I=\frac{V}{R}$  Using Ohm's Law, calculate the current of a wire that is 240 volts and has 120  $\Omega$  of reistance

• 2 A

• 0.2 A

• 20 A

• 4 A

Reflection is...

• The absorption of light into an object

• The passing of light through an object

• The bending of light as it bounces off a surface
