Write down the equation which links distance (s), force (F) and work done (W).
How to approach this question
Recall the formula for work done from the Physics Equations Sheet or from memory. Ensure you use the correct symbols as given in the question.
Full Answer
W = Fs
The equation for work done is a fundamental concept in energy and forces. It is defined as the product of the force applied and the distance moved in the direction of the force. The standard symbols are W for work done (measured in Joules, J), F for force (in Newtons, N), and s for distance (in metres, m). The equation is: W = F × s.
Common mistakes
✗ Writing the formula incorrectly, e.g., F = Ws or W = F/s.\n✗ Using incorrect symbols, e.g., E for work done or d for distance (though d is often accepted if defined).
