## Kinetic and Potential Energy

What is the difference between kinetic and potential energy?

With a partner, read the sections Energy of Motion and Energy of Position on pages 43 and 44 in textbook.

ANSWER THESE TEXT DEPENDENT QUESTIONS IN YOUR NOTEBOOK. BE PREPARED TO DISCUSS:

• What is kinetic energy?  Define and sketch an example in your notebook.
• How does kinetic energy depend on speed? Explain using textual evidence. "I know this because in the text it says ..."
• How does kinetic energy depend on mass? Explain using textual evidence. "I know this because in the text it says ..."
• What is potential energy? How does an object's mass and height factor into its potential energy.

## Man Riding Up Hill on Bike

Identify all the forms of energy that are represented in the photograph.

## Energy Transfer in a Trebuchet

As you watch the video, think about the changes in kinetic and potential energy.

## CAUTION: MISCONCEPTION

MISCONCEPTION: Energy CAN be created or destroyed.

TRUTH: Energy CANNOT be created or destroyed.  It can only change forms.

## Energy in a Roller Coaster

Watch the change in kinetic and potential energy!

Where is potential energy at its highest?  Where is it at its lowest?

Where is kinetic energy at its highest? Where is it at its lowest?
