What is mechanical energy?

Back

Mechanical energy is the energy that comes from the movement of objects. It is the sum of potential energy and kinetic energy.

From what source do plants receive energy?

Back

Plants receive energy from sunlight, which they use to perform photosynthesis.

Front

What type of energy does a microwave use to heat food?

Back

A microwave uses electrical energy to heat food.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from heat. It is created when the temperature of an object increases.

Front

What is electrical energy?

Back

Electrical energy is the energy resulting from the flow of charged particles, such as electrons.

Front

What is light energy?

Back

Light energy is the energy that is visible to the human eye and is produced by sources like the sun and light bulbs.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating objects and is transmitted through air, water, or solids.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a ball held at a height.

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.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
