If you moved the spacecraft magnet against a stronger force, what would happen? (check one)

• More potential energy would be stored in the magnetic field, and the spacecraft magnet would travel farther and faster.

• Less potential energy would be stored in the magnetic field, and the spacecraft magnet would not travel as far or as fast.

• The same amount of potential energy would be stored in the magnetic field, and the spacecraft magnet would travel the same distance at the same speed.

What affects the amount of potential energy stored in the magnetic field when a magnet is moved against a magnetic force?

• The magnetic force is stronger when the magnets are closer together. Moving against a stronger force stores more potential energy in the magnetic field.

• The magnetic force is weaker when the magnets are closer together. Moving against a weaker force stores more potential energy in the magnetic field.

Which claim does this Evidence Card A refute?

• Claim 2: Much more energy was in the launcher system on Wednesday than on Tuesday.

• Claim 3.A: The magnetic force was much stronger on Wednesday because the magnets were stronger.

• Claim 3.B: The magnetic force was much stronger on Wednesday because the magnetic force is stronger closer to the magnets.

Which claim supports Chapter 3 Question: Why was there so much more potential energy stored in the launcher system on Wednesday than on Tuesday?

• Claim 3.A: The magnetic force was much stronger on Wednesday because the magnets were stronger.

• Claim 3.B: The magnetic force was much stronger on Wednesday because the magnetic force is stronger closer to the magnets.
