Energy Introduction |
Watch the video.
Define "energy" on your notesheet.
Answer this question in your head:
How is energy related to force, motion, and work?
Watch the video.
Fill in the second section of your notesheet.
(name the two basic types of energy)
Similar to the rubber band, some objects can store energy by being stretched or compressed. This is called "elastic potential energy." Please define elastic potential energy on your note sheet and draw a picture as an example of an object that could have elastic potential energy.
Watch the video and answer this question in your head:
What is the second way that someone or something can store up potential energy?
Just like the ski jumper at the top of the hill, an object or person can store up potential energy by being raised up above the surface of the earth. This is called "gravitational potential energy." Please define this term on your notesheet, then draw a picture of an object or person who would have gravitational potential energy.
Watch this video. In your head, answer these questions:
When is potential energy changed into kinetic energy?
When is kinetic energy changed back into potential energy?
What does Mr. Eagle think is the "ultimate" example of potential and kinetic energy?
Read the chart at the bottom of your notesheet. Put a check mark in the correct column beside each situation to show whether it is an example of potential or kinetic energy. If it is potential energy, put an "e" or "g" to show whether it is elastic or gravitational.

You're finished!!
You will be responsible for getting your notesheet into your notebook on page 52.
See you on Monday!
