Magnetic Fields Review

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

How does kinetic energy relate to speed?

Back

Kinetic energy increases with the square of the speed. If speed decreases, kinetic energy also decreases.

Front

What is potential energy?

Back

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

Front

What happens to potential energy when moving away from a magnet?

Back

The potential energy increases because work is done against the magnetic force.

Front

What is the magnetic force?

Back

The magnetic force is the attraction or repulsion between magnetic poles. Like poles repel, while opposite poles attract.

Front

What does it mean for magnets to repel?

Back

When magnets repel, they push away from each other due to having the same poles facing each other.

Front

What is the effect of distance on magnetic force?

Back

The magnetic force decreases as the distance between magnets increases.

Front

What is the relationship between magnetic force and potential energy?

Back

As magnets are moved apart, potential energy increases due to the work done against the magnetic force.

Front

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

Back

They will repel each other, causing them to move away from each other.

Front

What is the principle of magnetic attraction?

Back

Magnetic attraction occurs when opposite poles of magnets are brought close together, pulling them towards each other.
