What is energy?

Back

Energy is the ability to do work or cause change. It can be found in different forms such as kinetic energy (movement) and potential energy (stored).

Front

What happens to energy when a hockey puck hits a barrier?

Back

Some of the energy is converted into sound and heat.

Front

Can you hold energy in your hand?

Back

No, you cannot hold energy in your hand. Energy is not a physical object.

Front

What makes things happen?

Back

Energy makes things happen. It is what causes movement and change.

Front

What happens to the energy transfer if you increase the weight of a moving object?

Back

The amount of energy it can transfer increases.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state. For example, a ball at the top of a hill has potential energy.

Front

What are some forms of energy?

Back

Some forms of energy include thermal energy (heat), mechanical energy (movement), chemical energy (stored in bonds), and electrical energy.

Front

What is the relationship between speed and energy?

Back

As an object moves faster, it has more energy to transfer.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves. It is a form of kinetic energy.
