Analysis of the experimental data:
| № опыта | Сила тяги (сила трения) F, Н | Расстояние s, м | Время движения t, с | Работа силы трения A, Дж | Мощность N, Вт |
|---|
| 1 | 0,5 | 0,10 | 1,8 | 0,050 | 0,028 |
| 2 | 0,6 | 0,097 | 2,55 | 0,0582 | 0,023 |
| 3 | 1 | 0,103 | 3,04 | 0,103 | 0,034 |
Observations from the table:
- The pulling force (F) increases from 0.5 N to 1 N as the number of weights increases (implied from trials 1 to 3).
- The distance (s) remains relatively consistent, around 0.10 m.
- The time (t) generally increases with the increase in pulling force, ranging from 1.8 s to 3.04 s.
- The work done (A) increases as the pulling force increases, from 0.050 J to 0.103 J. This is consistent with $$A = F \cdot s$$, as 'F' increases and 's' is roughly constant.
- The power (N) also generally increases with the pulling force, from 0.028 W to 0.034 W. This is consistent with $$N = A / t$$, where 'A' increases and 't' also increases. The increase in power is not linear due to the combined effect of changes in work and time.
