What is energy?

Back

Energy is the ability to do work or cause change. It exists in different forms, such as kinetic, potential, thermal, and sound energy.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating objects, which creates sound waves that travel through the air or other mediums.

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 the stored energy in an object due to its position or state. For example, a ball held at a height has potential energy.

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 electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It powers devices like lights and computers.

Front

What is light energy?

Back

Light energy is the energy that is visible to the human eye. It is produced by sources like the sun, light bulbs, and fire.

Front

What is an example of energy transformation?

Back

An example of energy transformation is when potential energy is converted to kinetic energy, such as when a roller coaster descends.

What happens to energy when you play a musical instrument?

Back

When you play a musical instrument, mechanical energy is transformed into sound energy.

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy can be converted into kinetic energy when an object moves. For example, a falling object converts potential energy to kinetic energy.
