<p><strong> Physics:</strong> Work is defined as the force applied along a displacement. \(W = \vec{F} \cdot \vec{d} = \|\vec{F}\| \, \|\vec{d}\| \cos \theta, \quad \text{where } \theta \) is the angle between force and displacement. For example, pushing a box at an angle; only the component of force in the direction of motion contributes to work.</p>
