Lab: 1D Kinematics The objective of this lab is to investigate the interrelation between the change in velocity and acceleration in the uniformly variable motion. One is required to verify authenticity of the distance equation covered by an object in this motion as a function of its acceleration and initial velocity. Go to: htt s: het.co|orado.edu en simulation le ac movin -man The interrelation between the change in velocity (the velocity increment) and acceleration in the uniformly variable motion is given by: Av v v0 a = Al' = l' l' 0 a - acceleration Av - the velocity increment At - the time increment v - final velocity v0 - initial velocity t - final time to - initial time whereas, the distance covered in this motion represents: d = v.At+ a ( At) 2 2 d - distance in the uniformly variable motion NOTE: You need to turn in individual reports. 1. Testable Question: a. How is related to in uniformly variable motion? b. How is related to in uniformly variable motion? 2. Hypothesis: On your own 3. Variables: On your own4. Materials: PhETsimulation, ruler 5. Procedure: Perform the experiment. Write the procedure with sufficient detail. I Set the acceleration under the \"Introduction \" tab. 2. Start the simulation and stop it after a short time. 3. Measure the time and achieved velocity. 4 Measure the distance using a ruler. 5 Make 8 measurements, starting the consecutive where you stopped previously. Your initial velocity for a given measurement is the nal from the previous one. Make 4 measurements for the positive acceleration and 4 for negative (altogether 8). 6. Calculate the theoretical acceleration and distance for each measurement. 7. The calculated distance will be used as accurate value in order to compute the percent error. 8. Click the tab \"Charts \" and perform the same measurement as above. At the end, take screen shot Cort sc) of the chart. 6. Designed/Data table: The usual 7. Analysis: a. Calculate acceleration and distance using the uniformly variable motion's equations. Show, at least.one calculation for each. b. Calculate the percent of errors. Show, at least, one calculation. c. Make graph with time on x and the velocity on y (use the screen shot). Approximate the graph with a known line, but only if such an approximation is possible. d. Make graph with time on x and the distance on y (use the screen shot). Approximate the graph with a known line, but only if such an approximation is possible. 8. Conclusion: Answer the question (part 1) as specific as possible. 9. Evaluation: a. Do the results support your hypothesis or disprove it? b. Did your results match the theory described by the interrelation between time and velocity? Also, between the time and the distance traveled? c. Comment on your percent error. d. Were your measurements precise? Were they accurate? 10. Further Explorations: Explain a way this lab could be improved. You must address technical (equipment) aspects and/or procedural improvements
