The Definition of Acceleration
To measure gravitational acceleration (g) using simple materials and strop mild to measure its period interval Results and summary:
According to the info on the dining tables and graphs below I found the gravitational acceleration (g) using the slops from the linear line of the (Velocity Vs . Time) charts to end up with -7. 43%, -4. 92%, and -12. 44% error for each trial 1, a couple of, and a few respectively.
After fixing the paper to a weight-metal, it was dropped and the content spinning moter might creat represents on the clear paper. After that the distances between the markings were very careful measured it had been not so exact and that may well be a source of problem especly when utilizing a long mettering stick. Follow that the possibility is miles was determined and the technice of strobe light occurred to gauge the time span and the alter of time that turned-out being 0. 024696s (strobe mild [2150hits/min] and a modification factor of 1. 13 caused it to be finally end up being [(2150x1. 13)/min 2429. 5hits/min]. As a result change of your time [(60s)/(2429. 5hits/min) 0. 024696s]. From that the velocity was calculated by simply dividing the change in distance by the enhancements made on time. There after the difference in velocities was simply calculated to break down it by change in the perfect time to get the velocity as displayed in the desks and charts.
Trial | Gravitational acceleration (g)| Accepted gravitational acceleration (g)| % mistake ([M-A]/A)x100%| 1| 907. twenty-three (cm/s/s)| 980 (cm/s/s)| -7. 43%
2| 931. 83 (cm/s/s)| 980 (cm/s/s)| -4. 92%
3| 858. 04 (cm/s/s)| 980 (cm/s/s)| -12. 44%
The percent error could possibly be caused by the run with the energy in the battery producing the moter spin slow to have longer distances among two represents. It was certainly not accurte to measure the diatances between two marks within the white conventional paper especially when by using a long meatering stick. Possibly after the modification factore of just one. 13 that was multiplet to the strobe light hits/min it may not be accurate...
