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
I think that the more PE there is in a system the less velocity or KE there will be.
I think that the more PE there is in a system the more velocity or KE there will be.
I do not think PE impacts speed or KE of a magnetic launch.
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
When the magnetic force is the greatest, the repelling magnets are farther apart
When the magnetic force is the greatest, the repelling magnets are closer together
Distance does not impact magnetic force, it is always the same around a magnet.
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
The magnetic force is strongest when attracting magnets are farther apart
The magnetic force is strongest when attracting magnets are closer together
Distance does not impact magnetic force, it is always the same around a magnet.
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
Monday will have the most PE because magnets are farthest apart and PE is greatest at a farther distance.
Tuesday will have the most PE because it is experiancing push and pull forces at the same time increase its PE.
Wednesday will have the most PE because the repelling magnets are move the most against the natural magnetic forces causing PE it increase.
