Law of Conservation of Energy

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.

What happens to energy when a football player kicks a ball?

Back

The ball gains kinetic energy as the player transfers energy to it.

Front

What does it mean when we say the total amount of energy in the universe remains constant?

Back

It means that the total energy does not change; it can only change forms, such as from potential to kinetic energy.

Front

What type of energy is associated with vibrating molecules?

Back

Sound energy is the energy of vibrating molecules that moves through matter.

Front

What occurs when you apply brakes on a bicycle?

Back

Friction causes some of the mechanical energy to be converted into thermal energy.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another.

Front

How does energy transfer occur in a system?

Back

Energy transfer occurs when energy moves from one object or system to another, often through work or heat.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

Can energy change forms?

Back

Yes, energy can change from one form to another, such as from potential energy to kinetic energy.
