Pushing a shopping cart across a supermarket floor: the harder you push (force $F$) and the further you walk down the aisle (distance $x$), the more work you do.

Work equals Force times distance: 'Work is Force in Motion' (WiFM).

In physics, work is said to be done when a force applied on an object displaces it. Mathematically, it is expressed as the scalar (dot) product of the force vector ($\vec{F}$) and the displacement vector ($\vec{x}$), which is written as $W = F \cdot x \cdot \cos(\theta)$. When the body is displaced strictly in the direction of the force, the angle $\theta = 0°$, so $\cos(0°) = 1$, simplifying the expression to $W = Fx$.

Always verify the angle between force and displacement vectors; if they are perpendicular ($\theta = 90°$), the work done is zero because $\cos(90°) = 0$.
