Question

A pendulum is timed, first for 20 swings and then for 50
swings:
time for 20 swings = 17 4s
time for 50 swings = 43 2s
Calculate the average time per swing in each case The answers are
slightly different Suggest some possible experimental reasons for
this

Vara · Accepted Answer

Case I:Average time per swing=17
420                                           =0
87 sCase II:Average time per swing=43
250                                           =0
864 sIn the second case, the average time is more accurate when compared tothe first case because of more number of observations

A pendulum is timed, first for 20 swings and then for 50 swings: time for 20 swings = 17.4s time for 50 swings = 43.2s Calculate the average time per swing in each case. The answers are slightly different. Suggest some possible experimental reasons for this.
