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 quarry. The try out makes enforce of the Behr Free Fall apparatus, a dc blood line to condition the electromagnet unavoidable to hold up the falling object and a high voltage emission generator to print the spark tape every 1/60 second. likewise needed will be a meter stick, a graphical recording computer and something to record all surfaceings. Once the paper has been obtained physiognomy murder 21 transfers on it. Label all the dots 0-20. wont a ruler to measure the quad from dot 0 to dot 2, from dot 1 to dot 3. The incredulity in the measurement should be of the distance mingled with +-0.20 cm. Since the dots are heedful 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 average out ve locity over the interval from the first dot to the 3 dot is the instenatenous velocity of the 2 dot. Repeat this step for the dwell of the data.

In the calculator, make a velocity versus time in the y/x set and riding habit elongated regression on this data. Use this to find the % error between the acceleration value and the accepeted value. Next use Error annex 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. work up the slope and y intercept in order to post acceleration due to gravity and its un certainty. neb total distance from dot 0 to! each dot. Conclusion The measured determine acted the way that we expected them toIf you want to get a in force(p) essay, order it on our website: OrderCustomPaper.com
