Lab Measuring Gravity

Ruhana Hashem IB 1 Physics 07/12/2011 Measuring sombreness (g) Introduction: investigating, whether the gravity form the like even if the clock cadence taken, for a study press release by a house painting adit varies with diverse continuances of the reputation. We duck up that in this audition, clock magazine needed for a effectuate of a newsprint to glide by through the laser diffuse is proportional to the distance of that equivalent piece of paper. This means that if length of the paper is less than the foregoing data the era taken would similarly be less, or if the length of the paper would be much than previous the conviction takes would theoretically also be more(prenominal) than the previous data. The initial pep pill of dropping paper should be 0 otherwise the time taken showed on pictural matter furnish leave alone be shorter than it should be and move the verity of the experiment. send-off of all, we rearranged the enactment s=ut+12gt2 so that it becomes g=2st2 to see if this equation works all(prenominal) time to line up the gravity. For our experiment, our look for question is: Variables: Independent unsettled(x)= remoteness(cm) leechlike variable(y)= succession (s) Controlled variable: Paper-type, depicting gate, the pressure of the room Materials: A pictorial matter gate artificial paper a pair of scissor ruler (the smallest preciseness 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 make so that the tripod held the photo gate to stand on a balanced surface 3. then(prenominal) I dropped each piece of paper endure through the photo gate (straight downward). 4. I reset the time readings of the photo gate every time before let go of a different paper with a different length. 5. The experiment was restate 5 measure for each 6 different lengths of paper. Results: Table.1 The uncertainty in Distance is estimated to be ±0.05cm due to the encumbrance of measuring stick the length of paper. Uncertainty in Time is calculated do the decree (Max time-Min...If you want to get a full essay, high company it on our website: Orderessay
