The Earth's Geographic North pole is Earth's magnetic ___________ pole.
South
The energy that is stored
potential energy
The energy of movement
kinetic energy
What is a natural metal that can interact with magnets?
The two sides of a magnet where the forces are strongest
the poles
How does magnetic force affect the energy in a system of magnets when the magnets are released and begin to move?
The magnetic force changes potential energy into kinetic energy.
DOUBLE POINTS - The place where potential energy is stored in a system of magnets.
magnetic field
The process of turning potential energy into kinetic energy
transfer
one of the two opposite ends of a magnet
magnetic pole
The poles that attract
What are opposite poles (north and south)?
When a magnet is moved in a certain direction against a force, the potential energy of the magnet system
increases
A way to increase the potential energy in a magnet system without moving the magnets
Stronger magnet
DOUBLE POINTS - The unit that measures potential or kinetic energy in an object?
Joules or kJ (J)
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 decreases as the kinetic energy decreases.
The poles that repel
What are the like poles (same, north to north and south to south)?
The change in the potential energy in the magnetic fields after the movement
Increasing
The change in potential energy when the magnet is moved
Increasing
The car that will have the greatest speed when the brakes are released
The orange car
Based on the magnetic field line diagrams, what will happen next with these sets of magnets? 
The magnets in Set 1 will attract, and the magnets in Set 2 will repel.
What direction will the trains move?
away from each other
The change in the potential energy if the car is moved toward the locked magnet. 
Decreasing
The magnet with the most potential energy if they are both moved one space closer to the center magnet
the pink magnet
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 increases because the train moves against the magnetic force.
Sharona puts two magnetic toy vehicles very close to each other. What will happen next, and why?

The toy vehicles will move away from each other because the magnetic force will push the toy vehicles apart.
Based on the magnetic field line diagrams, what will happen next with these two sets of magnets? 
The magnets in Set 1 will repel, and the magnets in Set 2 will attract.
