Forms of Energy (Unit 7 Review)

Front

What is mechanical energy?

Back

Mechanical energy is the energy that an object has due to its motion or position. It is the sum of kinetic energy (energy of motion) and potential energy (stored energy).

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object, which increases as the temperature rises.

Front

What is electrical energy?

Back

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

Front

What is light energy?

Back

Light energy is the energy that is visible to the human eye. It is produced by the movement of photons and is essential for photosynthesis in plants.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves. It travels through air, water, and solids.

Front

What types of energy does a toy oven use to bake cakes?

Back

A toy oven uses electrical and thermal energy to bake cakes.

Front

What type of energy causes ice cream to melt?

Back

Thermal energy (heat) causes ice cream to melt.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.
