The Story of Kinetic and Potential Energy

Kinetic and Potential Energy

What is the difference between kinetic and potential energy?

 

Kinetic and Potential Energy

READ TO LEARN

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.
