5.8A Energy Transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting electrical energy into mechanical energy.

Front

What is mechanical energy?

Back

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

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons, often used to power devices.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food and fuel.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often felt as heat.

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 vibrations of electrically charged particles.

Front

What device transforms electrical energy into mechanical energy?

Back

A fan transforms electrical energy into mechanical energy.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert light energy into chemical energy (food).

Front

What is an example of energy transformation in a balloon?

Back

When propane gas is used to lift a balloon, the energy transformation is chemical energy to thermal energy to mechanical energy.

Front

What happens during combustion?

Back

During combustion, chemical energy in fuel is converted to thermal energy, which can then be converted to mechanical energy.
