Question: 1 / 400

Which of the following is a correct unit for energy?

Newton

Joule

The correct unit for energy is Joule. The Joule is defined as the amount of energy transferred when one newton of force is applied over a distance of one meter. In the International System of Units (SI), energy is measured in joules, which is a derived unit of measurement that quantifies work, heat, or energy transfer.

Each of the other options represents different physical quantities:

- Newton is the unit of force, which measures the amount of force required to accelerate a one-kilogram mass by one meter per second squared.

- Watt is the unit of power, which measures the rate at which energy is transferred or converted; one watt is equivalent to one joule per second.

- Coulomb is the unit of electric charge, measuring the quantity of electricity transferred in a circuit.

Understanding the different units and their specific applications helps to clarify why joule is the appropriate choice when talking about energy.
