What is energy?

Back

Energy is the ability to do work or cause change. It can exist in various forms, such as mechanical, electrical, thermal, and chemical.

Front

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 is used to power devices like lights, toasters, and computers.

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 particles in an object.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow from a power source, through a conductor, and back to the power source.

Front

What is a light bulb?

Back

A light bulb is a device that produces light when electricity passes through it, converting electrical energy into light energy.

Front

What is the purpose of a switch in a circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity and turning devices on or off.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one place to another or from one form to another.

What is an advantage of using fluorescent bulbs?

Back

Fluorescent bulbs are more energy-efficient than traditional incandescent bulbs, reducing the amount of heat and electricity used.

Front

What happens when you push a switch down in a circuit?

Back

Pushing a switch down completes the circuit, allowing electricity to flow and turning on the connected device.
