Energy and Energy Transfer

Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work. It is energy based on an object's position or state.

Front

What type of energy is chemical energy?

Back

Chemical energy is a form of potential energy stored in the bonds of chemical compounds, like food or fuel.

Front

What happens when a person moves a ball up a ramp?

Back

There is a transfer of energy and work is done as the person applies force to move the ball against gravity.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

When does a ball have the most gravitational potential energy?

Back

A ball has the most gravitational potential energy at the top of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion. It depends on the mass and speed of an object.

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy can be converted into kinetic energy when an object is in motion, such as a ball rolling down a hill.

Front

What is an example of mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object. For example, a moving car has mechanical energy.

Front

What is sound energy?

Back

Sound energy is a form of energy produced by vibrating sound waves that can be heard.

Front

What is electrical energy?

Back

Electrical energy is the energy of moving electrons, commonly used to power devices and appliances.
