Grade 8 Law of Conservation of Energy

Front

What does the Law of Conservation of Energy state?

Back

The total amount of energy in a closed system remains constant; energy cannot be created or destroyed, only transformed.

Front

What is energy?

Back

Energy is the ability to do work.

Front

When does an object have the most gravitational potential energy?

Back

An object has the most gravitational potential energy when it is at its highest point.

Front

What type of energy transfer occurs when an object is dropped?

Back

Gravitational Potential Energy transforms into Kinetic Energy, which can then produce Sound Energy.

Front

What type of energy is associated with motion?

Back

Kinetic Energy.

Front

What type of energy is stored due to an object's position?

Back

Potential Energy.

Front

What happens to energy during a chemical reaction according to the Law of Conservation of Energy?

Back

The total energy before and after the reaction remains the same; it is conserved.

Front

What is an example of kinetic energy?

Back

A moving car, a running person, or a flowing river.

Front

What is an example of potential energy?

Back

A drawn bow, a book on a shelf, or water stored in a dam.

Front

What happens to the total energy in a closed system?

Back

The total energy remains constant; it can change forms but cannot be lost or gained.
