Unit 8 Energy Transformations and Transfers

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is used to power devices like lights and computers.

Front

What is electromagnetic energy?

Back

Electromagnetic energy is a form of energy that travels in waves and includes visible light, radio waves, and X-rays.

Front

Define gravitational potential energy.

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is an example of mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object, such as a moving car.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or batteries.

Front

What device converts chemical energy into electrical energy?

Back

A battery-powered flashlight converts chemical energy into electrical energy.

Front

What is an example of sound energy?

Back

Sound energy is produced when an object vibrates, creating waves in the air, like music from a speaker.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is energy of motion.
