Magnetic Fields Unit Review- 2024

Front

What is kinetic energy?

Back

The energy that an object has because it is moving.

Front

What is potential energy?

Back

The energy that is stored in an object or system.

Front

How do magnets affect potential energy?

Back

Magnets can store potential energy when they are positioned to attract or repel other magnetic objects.

Front

What happens to potential energy when an object moves closer to a magnet?

Back

More potential energy is stored as the object gets closer to the magnet.

Front

How can magnets cause objects to have kinetic energy?

Back

A magnetic force can convert potential energy stored in a magnetic field to kinetic energy.

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy can be converted into kinetic energy when an object is set in motion.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the effect of distance on potential energy in a magnetic field?

Back

The closer an object is to a magnet, the more potential energy it has.

Front

What is an example of energy conversion in a magnet?

Back

When a magnet pulls a metal object towards it, potential energy is converted to kinetic energy.
