A technician carries out four tests on an automatic sliding gate. In each test, the driving force acts in the direction in which the gate moves.
| Test | Driving force in N\mathrm{N}N | Distance moved in m\mathrm{m}m |
|---|---|---|
| 1 | 240 | 6.0 |
| 2 | 40 | 6.0 |
| 3 | 120 | 3.0 |
| 4 | 120 | 2.0 |
Which two tests transfer the same amount of energy mechanically to the gate?
Tests 1 and 3
Tests 2 and 4
Tests 3 and 4
Tests 1 and 2
