What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, chemical, and more.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state. For example, a rock at the top of a hill has gravitational potential 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.

Front

What is an example of kinetic energy?

Back

Examples of kinetic energy include a moving car, a flowing river, or a person running.

Front

What type of energy do batteries store?

Back

Batteries store chemical energy, which can be converted into electrical energy when needed.

Front

What happens to energy in a closed system?

Back

In a closed system, the total amount of energy remains constant; it can change forms but cannot be lost or gained.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in a substance.

Front

What is an example of potential energy?

Back

An example of potential energy is a stretched rubber band or water stored in a dam.
