Describing Energy

Front

What is gravitational potential energy?

Back

Gravitational potential energy is energy that is due to the gravitational forces between massive objects.

Front

What is chemical potential energy?

Back

Chemical potential energy is energy that is due to chemical bonds.

Front

Can energy be created or destroyed?

Back

No, energy can be transferred or changed from one type to another, but it cannot be created or destroyed.

Front

What is kinetic energy?

Back

Kinetic energy is energy due to motion. The kinetic energy of an object's motion depends on that object's mass and velocity.

Front

What type of energy is used when burning gasoline?

Back

Chemical energy is used when burning gasoline.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between mass and gravitational potential energy?

Back

Gravitational potential energy increases with an increase in mass.

Front

What happens to energy during a chemical reaction?

Back

Energy is either absorbed or released during a chemical reaction, depending on the nature of the reaction.

Front

What is the principle of conservation of energy?

Back

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

Front

What is an example of kinetic energy in everyday life?

Back

A moving car has kinetic energy due to its motion.
