FORMS OF ENERGY & ENERGY TRANSFORMATION

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 into mechanical energy for movement.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released during a chemical reaction.

Front

What is gravitational energy?

Back

Gravitational energy is the potential energy held by an object because of its height above the ground. The higher the object, the more gravitational energy it has.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, including light. It is the energy that travels through space and can be absorbed by objects.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance. It is often associated with heat.

Front

What is the process of generating electricity from coal?

Back

The process involves converting chemical energy in coal to thermal energy through combustion, then to mechanical energy using steam to turn turbines, and finally to electrical energy.

Front

What is an example of energy transformation in a lamp?

Back

When a lamp is plugged in, electrical energy is transformed into radiant energy (light) when the light comes on.

Front

What type of energy transformation occurs in a hawk when it eats a mouse?

Back

The transformation is from chemical energy (in the mouse) to mechanical energy (for flying).

Front

What is elastic energy?

Back

Elastic energy is the potential energy stored in an object when it is compressed or stretched, such as in a spring.
