What is the unit of measurement for work done?

The unit of measurement for work done is the Joule. Work is calculated as the product of force and displacement in the direction of the force. The formula for work is given by ( W = F \cdot d ), where ( W ) is work, ( F ) is the force applied, and ( d ) is the distance moved in the direction of the force.

In the International System of Units (SI), force is measured in Newtons (N) and displacement is measured in meters (m). When you multiply the force in Newtons by displacement in meters, the result is expressed in Joules (J). Specifically, 1 Joule is defined as the amount of work done when a force of 1 Newton moves an object 1 meter in the direction of the force.

The other units mentioned relate to different physical quantities: Newton is a unit of force, Watt is a unit of power which is the rate of doing work, and Pascal is a unit of pressure. Thus, they do not pertain to the measurement of work done.
