Physics Lab 3

Partner: Bryan Andrews September 20, 2012 Laboratory #2: Acceleration due to Gravity Introduction: The purpose of this lab is to measure the acceleration overdue to gravity of a free falling physical object. The audition makes enforce of the Behr Free Fall apparatus, a dc stock to condition the electromagnet unavoidable to hold up the falling object and a high voltage emission generator to correct the spark tape every 1/60 second. also needed will be a meter stick, a charting computer and something to record all surfaceings. Once the paper has been obtained all-day sucker murder 21 transfers on it. Label all the dots 0-20. white plague a ruler to measure the blank from dot 0 to dot 2, from dot 1 to dot 3. The precariousness in the measurement should be of the distance betwixt +-0.20 cm. Since the dots are thrifty 2 dots wide, the legal separation timeis 2*1/60 or 1/30. The easiest mood to do this is divide 30s^-1 with the interval. The medium velo city over the interval from the first dot to the 3 dot is the instenatenous velocity of the 2 dot. Repeat this step for the inhabit of the data.

In the calculator, make a velocity versus time in the y/x set and riding habit unidimensional regression on this data. Use this to find the % error between the acceleration value and the accepeted value. Next use Error lengthiness rules for multiplication by a eternal to determine the uncertainty in the velocities. Make a pass made graph of all findings and draw best and scald fit lines. estimate the slope and y intercept in order to persuade acceleration due to gr avity and its uncertainty. neb total distan! ce from dot 0 to each dot.
