An engineer tests four different mechanical prototypes by pulling them across a high-friction testing track. The forces required to pull each prototype and the distances moved are recorded in the table below:
| Prototype | Pulling force needed to move the prototype (N\text{N}N) | Distance moved along the track (m\text{m}m) |
|---|---|---|
| A | 8 | 5 |
| B | 12 | 4 |
| C | 15 | 6 |
| D | 25 | 3 |
On which prototype is the most work done?
Prototype A
Prototype B
Prototype C
Prototype D
67 exam-style questions on CIE IGCSE Physics 1.7.2 Work done. Each one has a worked solution and a mark scheme showing where the marks go.
