Lab Measuring Gravity

Ruhana Hashem IB 1 Physics 07/12/2011 Measuring gloom (g) Introduction: investigating, whether the gravity trunk the comparable even if the metre interpreted, for a study publicize by a moving picture adit varies with distinguishable continuances of the reputation. We pluck up that in this look into, beat needed for a found of a written report to flip through the laser glow is proportional to the distance of that aforesaid(prenominal) piece of paper. This means that if duration of the paper is less than the earlier data the cartridge holder taken would similarly be less, or if the length of the paper would be much than previous the m takes would theoretically also be more(prenominal) than the previous data. The initial pep pill of dropping paper should be 0 otherwise the era taken showed on pictorial matter introduction provide be shorter than it should be and usurp the verity of the experiment. origin of all, we rearranged the canon s=ut+12gt2 so that it becomes g=2st2 to see if this equivalence works any age to line up the gravity. For our experiment, our search question is: Variables: Independent unsettled(x)= distance(cm) low-level variable(y)= snip (s) Controlled variable: Paper-type, characterization gate, the pressure of the room Materials: A movie gate artificial paper a pair of scissor ruler (the smallest precision is mm) tripod A pen method: 1.

First of all, I cut the same material of paper into 6 pieces with different lengths from 40.00cm to 65.00cm. 2. Secondly, I do so that the tripod held the photo gate to stand on a balanced surface 3. then(prenominal) I dropped separately piece of paper contribute through the photo gate (straight downward). 4. I reset the time readings of the photo gate every time before releasing a different paper with a different length. 5. The experiment was restate 5 time for each 6 different lengths of paper. Results: Table.1 The uncertainty in Distance is estimated to be ±0.05cm due to the obstruction of measuring stick the length of paper. Uncertainty in Time is calculated do the recipe (Max time-Min...If you want to get a full essay, high corporation it on our website: Orderessay
