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.
Based on the magnetic field lines diagram, what will happen to these two sets of magnets?
Set 1 magnets will repel, set 2 magnets will attract
Set 1 magnets will attract, set 2 magnets will attract
Set 1 magnets will attract, set 2 magnets will repel
Both sets of magnets will repel
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.
Which statement accurately describes the change in potential energy?
The potential energy does not change, because the magnets in the system do not change.
The potential energy increases because Magnet 1 is moved against the magnetic force.
The potential energy decreases because Magnet 1 moves against the magnetic force.
The potential energy decreases because Magnet 1 moves in the same direction as the magnetic force.
Based on the magnetic field lines diagram, what will happen next with these sets of magnets?
In both sets the magnets will attract.
In both sets the magnets will repel.
In Set 1 the magnets will repel and in Set 2 the magnets will attract.
In Set 1 the magnets will attract and in Set 2 the magnets will repel.
Will these magnets attract or repel?
Attract
Repel
Neither
Both
A spaceship is traveling through space. Suddenly, its kinetic energy decreases. What is most likely to be true about the speed of the spaceship?
The speed increases as the kinetic energy is converted to speed.
The speed decreases as the kinetic energy decreases.
The speed remains the same because the kinetic energy and speed are not related.
The speed increases to make up for the decrease in kinetic energy.
How does magnetic force affect the energy in a system of magnets when the magnets are released and begin to move?
The magnetic force increases the potential energy in the system.
The magnetic force decreases the potential energy in the system.
The magnetic force changes kinetic energy into potential energy.
The magnetic force changes potential energy into kinetic energy.
Will these magnets attract or repel?
Attract
Repel
Will these magnets attract or repel?
Attract
Repel

The energy that is stored in an object or system
To provide evidence against a claim
One of the two opposite ends of a magnet
What will happen next?
The trains will move closer because the magnetic force will pull the trains together.
