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 do work when released.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

Where is potential energy greatest for an object on a hill?

Back

At the top of the hill.

Front

What happens to potential energy when an object falls?

Back

The potential energy converts to kinetic energy as the object falls.

Front

What is the relationship between height and potential energy?

Back

The higher an object is, the greater its potential energy.

Front

What happens to potential energy when magnets are moved apart?

Back

The potential energy increases because you are moving the magnets against the magnetic field.

Front

When do repelling magnets have the most potential energy?

Back

When they are close to each other.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

How does mass affect potential energy?

Back

The greater the mass of an object, the greater its potential energy at a given height.
