Magnetic Fields Review Flashcard #1

Front

What happens to potential energy when a magnetic object moves against the magnetic force?

Back

The potential energy increases.

Front

What happens to potential energy when a magnetic object moves in the same direction as the magnetic force?

Back

The potential energy decreases.

Front

What is the relationship between speed and kinetic energy?

Back

As speed increases, kinetic energy increases.

Front

What happens to two magnets when they are released while being held close together?

Back

They will move away from each other because the magnetic force pushes them apart.

Front

What is potential energy in the context of magnets?

Back

Potential energy is the energy stored in a system due to the position of the magnets relative to each other.

Front

How does moving a magnet toward another stationary magnet affect potential energy?

Back

The potential energy increases because the moving magnet is working against the magnetic force.

Front

What is the effect of distance on potential energy between two magnets?

Back

Increasing the distance between two magnets generally increases the potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What happens to the potential energy of a magnetic roller coaster car when it is moved away from a center magnet?

Back

The potential energy increases as it moves away from the magnet.

Front

What is the formula for kinetic energy?

Back

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