Magnetic Forces Test Review

Front

What happens to the potential energy of a system of magnets when they are moved apart?

Back

The potential energy decreases when the magnets are moved apart.

Front

In a magnetic roller coaster, which movement results in the largest increase in kinetic energy of the cart?

Back

Moving Cart 1 one space toward the launcher magnet results in the largest increase in kinetic energy because more potential energy is stored as the cart moves against the magnetic field.

Front

How can you increase the potential energy of a toy magnetic car on a track?

Back

By moving the lighter car one space to the left (toward the magnet), you increase its potential energy.

Front

What happens to the kinetic energy of a cyclist when their speed decreases?

Back

The kinetic energy decreases as the cyclist's speed decreases.

Front

Can potential and kinetic energy be converted back and forth in a system?

Back

Yes, by adding a force to a system, potential and kinetic energy can be converted back and forth.

Front

Define potential energy in the context of magnetic systems.

Back

Potential energy in magnetic systems is the energy stored due to the position of magnets relative to each other.

Front

What is kinetic energy?

Back

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

Front

Explain the relationship between potential energy and kinetic energy in a roller coaster system.

Back

As a roller coaster moves, potential energy is converted to kinetic energy as it descends, and kinetic energy is converted back to potential energy as it ascends.

Front

What role does the magnetic field play in energy conversion in magnetic systems?

Back

The magnetic field influences the potential energy of objects within it, affecting how much kinetic energy can be generated when they move.

Front

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

Back

As the distance between two magnets increases, the potential energy of the system decreases.
