Physics Lab 3

Partner: Bryan Andrews September 20, 2012 Laboratory #2: Acceleration receivable to Gravity Introduction: The purpose of this lab is to measure the speedup overdue to gravity of a free falling intention. The essay makes enforce of the Behr Free Fall apparatus, a dc origin to condition the electromagnet unavoidable to hold up the falling object and a high voltage emission generator to prick the spark tape every 1/60 second. similarly needed will be a meter stick, a interpreting computer and something to record all surfaceings. Once the paper has been obtained check murder 21 transfers on it. Label all the dots 0-20. using up a ruler to measure the outgo from dot 0 to dot 2, from dot 1 to dot 3. The incertitude in the measurement should be of the distance in the midst of +-0.20 cm. Since the dots are careful 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 fair velocity over t he interval from the first dot to the 3 dot is the instenatenous velocity of the 2 dot. Repeat this step for the slumber of the data. In the calculator, make a velocity versus time in the y/x set and riding habit one-dimensional regression on this data. Use this to find the % error between the acceleration value and the accepeted value. Next use Error genesis 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. deem the slope and y intercept in order to extend acceleration due to gravity and its uncertainty. neb total distance from dot 0 to each dot.
