The work done by a variable force is best found from:

  1. its maximum value × total displacement
  2. the gradient
  3. the area under its force–displacement graph
  4. its minimum value × total displacement
Answer

C) the area under its force–displacement graph

The force changes, so integrate (find the area). SLO P-11-B-30 · Application
