What is the SI unit of energy?

The SI unit of energy is the Joule (J).

Is a Newton the SI unit of energy?

A Newton (N) measures force, not energy.

Is a Watt the SI unit of energy?

A Watt (W) is the SI unit of power, which is the rate of energy transfer.

Is a Pascal the SI unit of energy?

A Pascal (Pa) is the SI unit of pressure. It measures force per unit area.

Study Notes

SI Unit of Energy

The correct SI unit of energy is the Joule (J).
A Joule is defined as the energy transferred to or from an object when a force of one Newton acts on that object in the direction of its motion through a distance of one metre.
It's a derived unit, meaning it's composed of other fundamental SI units.
The relationship can be mathematically expressed as 1 Joule = 1 Newton × 1 metre.
Other units of energy, such as the kilowatt-hour (kWh) and the calorie, are commonly used, but they are not part of the SI system.
The Joule is a fundamental unit for measuring energy in scientific contexts and engineering applications.
The SI unit for power is the Watt (W), which is defined as one Joule per second (1 W = 1 J/s).
The Newton (N) is the SI unit for force.
The Pascal (Pa) is the SI unit for pressure.
