Here's why:

* Force: A push or pull that can cause a change in motion.

* Displacement: The change in an object's position.

When a force acts on an object and causes it to move a certain distance, work is done.

Formula for work:

Work (W) = Force (F) × Displacement (d)

Units:

* Work is measured in joules (J).

* Force is measured in newtons (N).

* Displacement is measured in meters (m).

Important Note: The work done is only considered when the force and displacement are in the same direction. If the force and displacement are perpendicular, no work is done.
