What is measured in 'joules'?

Correct option is C

The correct answer is (c) Energy

• The joule (J) is the SI unit of energy. It measures the amount of work done or heat transferred.

• One joule is defined as the energy expended when a force of one newton moves an object one meter in the direction of the force.

Information Booster:

• Velocity is measured in meters per second (m/s).

• Force is measured in newtons (N).

• Power is measured in watts (W), where 1 watt = 1 joule/second.

• Energy can take different forms such as kinetic energy, potential energy, thermal energy, etc., all measured in joules.

Additional Information:

• The term "joule" is named after James Prescott Joule, an English physicist known for his work in the field of thermodynamics.

• In electrical terms, 1 joule is also the energy consumed when 1 watt of power is used for 1 second.
