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.

"I think Claim (A/B) is most correct because ..."

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
"The magnet and rode have potential energy because ...
The potential energy increases in the bottom because ... "

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?
