Analysis of the experimental data:

№ опытаСила тяги (сила трения) F, НРасстояние s, мВремя движения t, сРабота силы трения A, ДжМощность N, Вт
10,50,101,80,0500,028
20,60,0972,550,05820,023
310,1033,040,1030,034

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.
