Back

distance

Front

A magnetic force is _______ closer to a magnet.

Back

stronger

Front

A magnetic force can convert potential energy in a magnetic field to _______ energy.

Back

kinetic

Front

In a system of magnets, there is a _______ force between like poles and an _______ force between opposite poles.

Back

repelling, attracting

Front

Moving a magnet against a stronger magnetic _______ transfers more energy into the magnetic field.

Back

force

Front

Creating a _______ of a magnetic system and defining its parts helps scientists test and explain the relationship between force and energy.

Back

model

Front

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

Back

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

Front

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

Back

The potential energy increases.

Front

What happens to the potential energy of the system if Magnet 2 moves against the magnetic force?

Back

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