What will happen next?

• The trains will move closer because the magnetic force will pull the trains together.

• The trains will not move because the magnets are not touching.

• The trains will move away from each other because the magnetic force will push the trains apart.

• The trains will move away from each other because the magnets are not touching.

What happens to the potential energy?

• The potential energy does not change because the magnets in the system do not change.

• The potential energy increases because Magnet 2 moves against the magnetic force.

• The potential energy decreases because Magnet 2 moves against the magnetic force.

• The potential energy decreases because Magnet 2 moves in the same direction as the magnetic force.

Which move will result in the greatest potential energy increase?

• Moving the cart on Track 1 one space to the right.

• Moving the cart on Track 2 one space to the left.

• Moving the cart on Track 2 one space to the right.

• All moves will result in the same increase in potential energy.

What will happen when these magnets are let go?

• The magnets will not move because they are not touching.

• The magnets will move closer to each other because the magnetic force will pull them together.

• The magnets will move away from each other because the magnets are not touching.

• The magnets will move away from each other because the magnet force will push them apart.

What happens to the potential energy in the system, when the magnetic train is moved away from the stationary magnet?

• The potential energy increases because the magnet is moved against the magnet force.

• The potential energy decreases because the magnet is moved against the magnet force.

Which movement will result in the greatest potential energy increase?

• Moving Car 1 one space toward the center magnet.

• Moving Car 2 one space away from the center magnet.

• Moving Car 2 one space toward the center magnet.

• All movements will result in the same change in potential energy.

A spaceship is traveling through space. Suddenly, its speed increases. What can you say about the kinetic energy of the spaceship?

• The kinetic energy increases as the speed increases.

• The kinetic energy decreases as it is converted to speed.

• The kinetic energy stays the same because kinetic energy and speed are unrelated.

• There is no way to determine what happened to the kinetic energy.

What happens to the energy in a system of magnets when the magnetic force causes two magnets to move?

• The potential energy in the system increases.

• The kinetic energy in the system decreases.

• Some of the potential energy is converted to kinetic energy.

• Some of the kinetic energy changes to potential energy.

Julia puts two magnetic toy trains very close to each other on a track. What will happen next, and why?

• The trains will move toward each other because the magnetic force will pull the trains together.

• The trains will move apart because the magnetic force will push the trains away from each other.

• The trains will not move because the magnets are not touching.
