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 speedup overdue to gravity of a free falling object. The try makes enforce of the Behr Free Fall apparatus, a dc credit to condition the electromagnet unavoidable to hold up the falling object and a high voltage emission generator to crossbreed the spark tape every 1/60 second. in like manner needed will be a meter stick, a graphical recording computer and something to record all surfaceings. Once the paper has been obtained sic murder 21 transfers on it. Label all the dots 0-20. workout a ruler to measure the outer space from dot 0 to dot 2, from dot 1 to dot 3. The incredulity in the measurement should be of the distance surrounded by +-0.20 cm. Since the dots are measured 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 clean velocit y over the interval from the first dot to the 3 dot is the instenatenous velocity of the 2 dot. Repeat this step for the respire of the data.

In the calculator, make a velocity versus time in the y/x set and riding habit running(a) regression on this data. Use this to find the % error between the acceleration value and the accepeted value. Next use Error wing 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 communicate acceleration due to gravity and its u ncertainty. neb total distance from dot 0 t! o each dot.
