Energy and Engineering Review

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as thermal, mechanical, electrical, 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 thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in a substance.

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 a circuit?

Back

A circuit is a closed loop that allows electric current to flow. It typically includes a power source, conductors, and a load (like a light bulb).

Front

What is a switch in an electric circuit?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of electricity.

Front

What happens when you connect batteries in series?

Back

Connecting batteries in series increases the total voltage of the circuit, allowing more current to flow.

Front

What is the role of a light bulb in a circuit?

Back

A light bulb converts electrical energy into light energy, allowing us to see.

Front

What is the principle of energy conservation?

Back

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

Front

What is a catapult?

Back

A catapult is a device that uses mechanical energy to launch an object, such as a cork, into the air.
