IB Physics HL A.3.4 Work by constant force
Practise constant-force work calculations by linking force and displacement, spotting zero-work cases, and relating work to energy change.
How this is tested
- apply W = Fs for a constant force and displacement, then match the result to an energy change
- decide zero work by checking on a diagram that force stays perpendicular to displacement
- at terminal speed, use work = mg(vt) to find work done on the air over a short time
