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, we say work has been done. The amount of work done is directly proportional to both the force applied and the distance the object moves.

Formula for Work:

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

Units:

* Work is measured in Joules (J)

* Force is measured in Newtons (N)

* Displacement is measured in meters (m)

Important Note:

Work is only done when the force and displacement are in the same direction. If the force is perpendicular to the displacement (like pushing a wall), no work is done.
