🧠 Memory Aid
"Work = Force × Shift": The 's' in W = Fs stands for the shift (displacement) in the direction of the force. If there's no shift in the force direction, there's no work.
The "W.F.S." triangle: Draw a triangle with W at the top, F and s at the bottom corners. Cover the one you want: W = F × s; F = W ÷ s; s = W ÷ F.
Joule = Newton-metre: Remember "J = Nm" — 1 Joule is 1 Newton acting through 1 metre. This link between energy and force-times-distance is the whole point of work!
