Document Summary

Hedonism: pleasure/pain as dichotomy determining value: narrow hedonism, preference hedonism: What pains and pleasure have in common is their relation to our preferences and desires fulfills individual preference. An experience is pleasant if it is preferred life goes better if it goes as you prefer it to go. About our present state of mind/consciousness introspectively discernible, affecting our states of mind. Problem: better for me to believe i am not being deceived, irrelevant to whether or not my belief is false. It is better for you to believe you are not being deceived, even if your belief is false, as long as it doesn"t affect your state of mind. Desire fulfillment: what would best fulfill someone"s desires: unrestricted version: fulfillment of all my desires throughout life. Problem: does my life really go better if desires i had about someone else are fulfilled without my knowledge: success version: Only count desires about one"s own life.

Could you please proofread and correct scientifically andgrammatically my work, thanks ^_^

Here itis:
The percentage error was found to be 0.186% and 6.66%respectively.

This implies that the predicted value of the freefall accelerationis fairly accurate while the predicated value of deceleration isnot as much. The encountered errors were due to severalexperimental and human limitation was that the experiment involved.The experimental limitation was due to the uncertainty of theclinometer which was ± 0.5o.

I.e. In our calculation, a difference of 0.5o can lead to adifference of 40 - 80 cm in height as shown below:

The human limitations was due to the human eye being unable todetect the exact point on the track at which the gondoladecelerates. This is because the braking happened very quickly.This adds an uncertainty to the location of deceleration when theangels are being measured.

In addition, the human ability cannot decide on the exact period oftime at which the gondola freefalls or decelerates. This is due tothe human reaction speed being unable to exactly determine thestart time of the momentary freefall and deceleration. The timetaken for humans to react cannot be measured thus it cannot besubtracted from the findings to get an accurate timing.

All of these limitations that have affected the accuracy of theresults could be avoided to some extent by marking the exact zonesrequired on the track of the giant drop as well as using anelectronic angle measurer to measure the angles . Additionally, theusage of an electronic timer to measure periods of the freefall anddeceleration is also suggested.

During the analysis, finding an average to the deceleration in theaccelerometer reading (using Logger Pro) was only estimated usingthe human naked eye. This is because an average could not be takenelectronically. Thus, there is also some uncertainty involved inthe theoretical value.

NOTE:

The value for freefall acceleration obtained from thevideo-analysis technique was 9.754 ± 0.3237 m/s2. 9.754 m/s2 has apercentage error of :
0.469%

This value indicates it is fairly accurate and can be used as aconforming result to the theoretical value. The error involved isdue to the fact that the video was shaking, thus plotting thevelocity/ time graph of the gondola at different times wasnegatively affected; although the axes was roughly re-set at everyframe.
