Magnetic Fields Chapter 2 Review

In a computer simulation, Jeffrey moves a magnet (Magnet 2) toward another magnet (Magnet 1) that cannot move. What happens to the potential energy in the system of magnets?

• 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.

Abdul moves a magnetic toy train away from a magnet that cannot move. What happens to the potential energy in the system of magnets during the movement?

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

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

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

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

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 kinetic energy changes into potential energy.

• Some potential energy changes into kinetic energy.

In a computer simulation, Juan moves a magnet (Magnet 1) closer to another magnet (Magnet 2) that cannot move. 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 moves 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.

Trevor moves a magnetic toy train away from a magnet that cannot move. What happens to the potential energy in the system of magnets during the movement?

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

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

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

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

What is kinetic energy?

• The energy that is stored in an object or system

• To push objects away from each other

• The energy that an object has because it is moving

• To move from one object to another
