A linear actuator moves a steel pin in a straight line. The position of the pin is measured from a fixed reference point.
In each test, a constant force acts in the direction in which the pin moves.
| Test | Force in N | Initial position in m | Final position in m |
|---|---|---|---|
| A | 25 | 0.018 | 0.058 |
| B | 40 | 0.030 | 0.050 |
Calculate the work done on the pin in each test.
A student concludes that Test B transfers more energy to the pin because the force is greater.
Evaluate the student's conclusion using your answers to part (a).
