Create two models. In one model, show two magnets that will attract. In the other model show two magnets that will repel. Include magnetic field lines for both.

Part 1

Part 2

Test 2: What is the difference in potential energy between each of the launcher systems?

CFS:

• Accurately describes the relationship between magnetic field lines/magnetic postion and PE in magnetic systems"In attracting magnets PE is greatest when ...

In repelling magnets PE is greatest when... "

(Think: Look at distance between magnets, what is it greatest for each pair?)

How do you think these differences impact the velocity of the launch?

CFS:

• Accurately describes the relationship between magnetic position and the force/field in a system

• Accurately describes the relationship between force and acceleration

Part 1:

Describe the placement of the magnets when the magnetic force between each of the launcher systems is the greatest?

CFS:

- Accurately describes the relationship between magnetic field lines/magnetic postion and magnetic force

Describe the placement of the magnets when the magnetic force between each of the launcher systems is the greatest?

CFS:

• Accurately describes the relationship between magnetic forces and potential energy

Describe which day will have the most PE energy in the launch system.

CFS:

• Accurately describes the relationship between magnetic position and the force/field in a system

• Accurately describes the relationship between magnetic forces and the movement of magnets in a system
