Magnets Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or arrangement. It can be converted to kinetic energy when the object moves.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

What happens to potential energy when two magnets are moved farther apart?

Back

The potential energy increases as the magnets are moved farther apart due to the increase in the distance between their magnetic fields.

Front

What happens to kinetic energy when two magnets are released and move apart?

Back

The kinetic energy increases as the magnets move apart, while potential energy decreases.

Front

What is the relationship between magnetic poles?

Back

Opposite poles of magnets attract each other (north to south), while like poles repel each other (north to north or south to south).

Front

How can you increase the potential energy in a magnetic system?

Back

You can increase the potential energy by moving the magnets farther apart.

Front

What does it mean when two magnets are repelling each other?

Back

It means that the like poles of the magnets are facing each other, causing them to push away from one another.

Front

What is the principle of conservation of energy in a magnetic system?

Back

The total energy in a closed system remains constant; energy can change forms (from potential to kinetic) but cannot be created or destroyed.

Front

What is the effect of distance on the strength of a magnetic force?

Back

The strength of the magnetic force decreases as the distance between the magnets increases.

Front

What is a magnetic field?

Back

A magnetic field is the region around a magnet where magnetic forces can be detected and where other magnetic materials experience a force.
