What is the SI unit of work?

Watt
Meter
Joule
Kilogram

The correct answer is: Joule

The SI unit of work is the Joule. Work in physics is defined as the amount of energy transferred when a force is applied to an object and that object moves a certain distance. Mathematically, work is represented as the product of force and displacement in the direction of the force. Specifically, one Joule is equivalent to the amount of work done when a force of one newton moves an object one meter in the direction of the force. Therefore, Joules are a fundamental unit in the International System of Units (SI) for measuring work and energy. The other options represent different physical quantities. The Watt is a unit of power, which measures the rate of doing work. The Meter is a unit of length, which measures distance, and the Kilogram is a unit of mass. None of these alternatives describe work in the context defined by physics.
