Amplify Magnetic Fields Chapter 2

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

How does height affect potential energy?

Back

The higher an object is positioned, the greater its potential energy due to the gravitational force acting on it.

Front

What is the formula for gravitational potential energy?

Back

The formula is PE = mgh, where PE is potential energy, m is mass, g is the acceleration due to gravity, and h is height.

Front

What is a magnetic field?

Back

A magnetic field is a region around a magnet where magnetic forces can be observed. It is created by moving electric charges.

Front

How does a magnet store potential energy?

Back

A magnet stores potential energy when it is positioned within a magnetic field, and the energy can be released when the magnet is moved.

Front

What happens to potential energy when an object is lowered?

Back

When an object is lowered, its potential energy decreases because it is moving closer to the ground.

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy can be converted into kinetic energy when an object is allowed to move, such as when it falls.

Front

What is an example of elastic potential energy?

Back

An example of elastic potential energy is the energy stored in a stretched rubber band or the elastic of a slingshot.

Front

What is the role of a slingshot in storing potential energy?

Back

A slingshot stores potential energy in its elastic band when it is pulled back, which is then converted to kinetic energy when released.

Front

What direction should a magnet be moved to increase potential energy in a magnetic field?

Back

A magnet should be moved away from the magnetic field to increase its potential energy.
