Energy Transformations and Waves

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting chemical energy in food to kinetic energy when we move.

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 gravitational potential energy?

Back

Gravitational potential energy is the energy stored in an object as it is raised to a height against the force of gravity.

Front

What type of energy does a battery store?

Back

A battery stores chemical energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and speed.

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 device transforms electrical energy into mechanical energy?

Back

An electric motor transforms electrical energy into mechanical energy.

Front

What happens to energy when a rubber band is stretched?

Back

When a rubber band is stretched, it stores elastic potential energy, which is released as kinetic energy when it snaps back.

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is produced by the vibration of electrically charged particles.

Front

What is an example of energy transformation in a flashlight?

Back

In a flashlight, chemical energy from the battery is transformed into electrical energy, which is then transformed into light energy.
