Magnetic Fields Review

Front

What is a magnetic field?

Back

A magnetic field is a 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.

What happens when two like poles of magnets are brought close together?

Back

They repel each other, meaning they push away from each other.

Front

What happens when two opposite poles of magnets are brought close together?

Back

They attract each other, meaning they pull towards each other.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. In magnets, it can be related to their position relative to each other.

Front

How does distance affect the strength of a magnetic force?

Back

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

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed; as speed increases, kinetic energy increases.

Front

What is the principle of conservation of energy?

Back

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

Front

What is the effect of magnetic force on potential energy in a system of magnets?

Back

Magnetic force can convert potential energy into kinetic energy when magnets are released and allowed to move.

What is the role of a blue magnet in a magnetic cart system?

Back

The blue magnet serves as a fixed point that can influence the potential energy of the magnetic carts based on their position relative to it.
