Back

Opposite poles attract.

Front

What happens when like poles of magnets are brought together?

Back

Like poles repel.

Front

Why does a compass point north?

Back

The positive north side of the compass magnet is attracted to the magnetic south pole.

Front

What is the relationship between speed and kinetic energy?

Back

The kinetic energy increases as the speed increases.

Front

What is potential energy?

Back

The energy that is stored in an object or system.

Front

What are magnetic field lines?

Back

Imaginary lines that represent the direction and strength of a magnetic field.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy = 1/2 mv² (where m is mass and v is velocity).

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

What is a magnetic field?

Back

A region around a magnet where magnetic forces can be detected.

Front

How do electric fields interact with charged objects?

Back

Electric fields exert forces on charged objects, attracting or repelling them.
