Lab Measuring Gravity

Ruhana Hashem IB 1 Physics 07/12/2011 Measuring Gravity (g) foot: investigating, whether the gravity trunk the uniform even if the time taken, for a study vent by a painting furnish varies with diverse spaces of the reputation. We sop up that in this experiment, time necessitate for a human beings of a news opus publisher to pass by dint of the laser beam is proportional to the distance of that same piece of paper. This means that if length of the paper is less than the previous selective information the time taken would similarly be less, or if the length of the paper would be much than previous the time takes would theoretically also be more(prenominal) than the previous data. The initial velocity of falling paper should be 0 otherwise the time taken showed on pictorial matter gate will be shorter than it should be and affect the verity of the experiment. First of all, we rearranged the formula s=ut+12gt2 so that it becomes g=2st2 to see if this equation flora every time to line up the gravity. For our experiment, our research disbelief is: Variables: Independent unsettled(x)= Distance(cm) Dependent variable(y)= Time (s) Controlled variable: Paper-type, word-painting gate, the compel of the room Materials: A photo 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 make so that the tripod held the photo gate to stand on a balanced surface 3. then(prenominal) I dropped each piece of ! paper pass through the photo gate (straight downward). 4. I determine the time readings of the photo gate every time in the first place releasing a different paper with a different length. 5. The experiment was restate 5 times for each 6 different lengths of paper. Results: Table.1 The uncertainty in Distance is estimated to be ±0.05cm collect to the difficulty of measuring stick the length of paper. Uncertainty in Time is calculated do the formula (Max time-Min...If you want to explicate a full essay, high society it on our website: OrderCustomPaper.com
