Objective: SWBAT use models to describe the transfer of potential to kinetic energy in a system of magnets.

Create a model to predict how potential energy (PE) and kinetic energy (KE) change when two magnets repel.

Shade in the bar graphs under each panel to show how much potential energy and kinetic energy you think the system has at each time.

Guided Notes: 

Vocabulary:
Transfer: to move from one object to another or one place to another

Which claim do you think is most correct?
- Claim A: Potential energy increases when a magnet is moved with (in the same direction as) the magnetic force.

- Claim B: Potential energy increases when a magnet is moved against (in the opposite direction from) the magnetic force.

Practice:

Carefully read your evidence card and write an answer to your specific prompt. Students assigned to #1 will answer the prompt below. Students assigned to #2 should press NEXT to see their prompt. Students assigned to #3 should press NEXT twice to see their prompt.
Answer your prompt, using the vocabulary words listed in the Word Bank below.
After everyone in your group has had a chance to write, take turns introducing your prompts and sharing your responses.
While one student is presenting, the other two listen carefully.
After each student presents, the other students in the group can ask questions or make comments

The kinetic energy of the attracted magnet and iron rod came from potential energy in the system.

How did potential energy get stored in the magnet/iron rod system?
CFS:
Accurately describes how energy is transferred from one object to another
Accurately describes the relationship between magnetic energy and movement of magnets in a system

In a computer simulation, Jeffrey moves a magnet (Magnet 2) toward another magnet (Magnet 1) that cannot move. What happens to the potential energy in the system of magnets?

*Think:
1. what is the natural direction of motion (natural force)
2. does the motion increase or decrease PE based on its movement with or against the magnetic force?
