What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It powers devices like lights, computers, and appliances.

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the energy of moving particles within an object.

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye. It is produced by the vibrations of electrically charged particles.

What is sound energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the top of a hill has potential energy.

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.

What is a turbine?

Back

A turbine is a machine that converts fluid (like water or air) into mechanical energy. It is often used in power generation.

How does a lightbulb work?

Back

A lightbulb converts electrical energy into light energy through a filament that heats up and produces light when electricity flows through it.
