What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or arrangement. It has the potential to be converted into kinetic energy.

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.

How do magnets interact with each other?

Back

Magnets can attract or repel each other depending on their orientation. Opposite poles attract, while like poles repel.

Front

What happens to potential energy when two magnets are brought closer together?

Back

The potential energy in the system increases as the magnets are brought closer due to the increase in magnetic force.

Front

What is the relationship between potential energy and kinetic energy in a system of magnets?

Back

Potential energy can be converted into kinetic energy when magnets are released and allowed to move.

Front

What is a magnetic field?

Back

A magnetic field is the region around a magnet where magnetic forces can be detected. It is represented by field lines that show the direction and strength of the magnetic force.

Front

What is the effect of distance on magnetic force?

Back

The magnetic force decreases as the distance between two magnets increases.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the significance of the north and south poles of a magnet?

Back

The north and south poles of a magnet are the points where the magnetic force is strongest. They determine how magnets will interact with each other.

Front

How does moving a magnet affect its potential energy?

Back

Moving a magnet closer to another magnet increases its potential energy, while moving it away decreases its potential energy.
