What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons, which can be used to power devices like lights and appliances.

Front

What is mechanical energy?

Back

Mechanical energy is the energy of motion, which can be kinetic (moving) or potential (stored) energy.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or batteries, which can be released during a chemical reaction.

Front

What device converts electrical energy into mechanical energy?

Back

A blender converts electrical energy into mechanical energy to mix or chop food.

Front

What is the primary energy transformation in a television?

Back

The primary energy transformation in a television is electricity to sound and light.

Front

What is the role of a stereo in energy transformation?

Back

A stereo transforms chemical energy from batteries into electrical energy, which is then converted into sound energy.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position.

Front

What is thermal energy?

Back

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