2020 Energy Transfers

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one system or object to another, often resulting in a change in form.

Front

What are the main forms of energy?

Back

The main forms of energy include thermal, mechanical, electrical, chemical, and sound energy.

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 an object.

Front

What is mechanical energy?

Back

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

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is commonly used to power devices.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves, which can be heard when they reach a person's or animal's ear.

Front

What is an example of energy conversion?

Back

An example of energy conversion is a toaster converting electrical energy into thermal energy to toast bread.

Front

What happens during the conversion of electrical to mechanical energy?

Back

During this conversion, electrical energy is used to create motion, such as in electric motors.

Front

What is an example of chemical to mechanical energy conversion?

Back

An example is a car engine converting the chemical energy in gasoline into mechanical energy to move the car.
