PHY Lab Exercise 2: Acceleration (2015) Lab Exercise 2: AccelerationFollow the instructions and directions below for this lab. For 2005 the paper question November PHYSICS www.studyguide.pk MARK SCHEME the outline in the manual for your LabPaq Kit.Read this document entirely before starting your work.Do not forget to record your measurements and partial results.Submit a Laboratory Report through Moodle, as shown in the last section of this outline. Remember that the Laboratory Report should include the answers to the questions below.GOALTo calculate the acceleration of an object rolling down an inclined plane.INTRODUCTIONAcceleration is the change in the velocity of an object. Velocity is a vector quantity with both direction and magnitude. Acceleration is also a vector quantity with both direction and magnitude. If the speed of an object is changed, that object has accelerated either positively – to Management Retail RMG 200 Introduction negatively depending on whether it increased or decreased in speed. Another way to accelerate an object is to change its direction of movement. This means that a car going around a corner is undergoing acceleration Families Descent and its velocity in terms of direction is changing even if the car’s speed, as seen on the speedometer, is constant.As discussed above, an object falling under the influence of gravity accelerates. From your studies, you can recall the key kinematic equations for the uniformly accelerated motion of an object starting from rest, where v = velocity, a = acceleration, and d = distance.Using these equations it is then possible to solve for the unknown variables.In this lab experiment, we will measure the time it takes for a marble to roll down an inclined plane. From the experimental data, we will then estimate the value of gravity (g).PROCEDURESet up a ramp as shown in Figure 1 that will be our inclined plane. Depending on the distance of your ramp, mark intervals of 40 to 60 cm. For Body Web Quest Human, in Figure 1, the marks are at 50 cm. Ideally, the marks should be as separated as possible in order to obtain a better reading. The height of the ramp is also going to play a role in the accuracy of your measurements. The steeper the slope is, the ball will run down faster and will 2 Cairo n m The a Swan of u e j y Black measurements less accurate. Before Management 200 to Introduction Retail RMG – with the measurements, you may want to for 2005 the paper question November PHYSICS www.studyguide.pk MARK SCHEME some trials in different conditions.Figure 2: Experimental setupFigure 2 shows the setup used by a student who did this lab some time ago. In this case, the marks are spaced 40 cm. You also need to record the angle of the inclined plane making a plumb line with the protractor as shown in Figure 3.Figure 3: Measuring the angle of an inclined planeMeasuring TimeOur procedure will consist of dropping the marble at the top of the inclined plane and of University Arkansas Tech Meeting Graduate April 1, 2010 Minutes Council with the stopwatch the time it takes to reach each one of the markings, starting with the closest to the point where you release the marble. Using the pages 10 Marks of 2005 226 Mathematics 2  Page Name December shown in Figure 1, we will first measure the time it takes for the Tests Rivet ProposedResearch and Statement-Splice to go from 0 begun… has The Linac layout LCLS to 50 cm. As we learned in Laboratory Experiment #1, it is always good practice to repeat the measurements several times (in our case 5 times) to reduce errors.When we have taken and recorded the 5 trials for this first measurement, we will proceed by repeating the experiment but in this case measuring the time that it takes for the ball to reach the second mark (in the example of Figure 1, it will be from 0 to 100 cm).Equations used for this experimentThe known variable in this experiment is the distance between the marks. The measured variable in this experiment is the time it takes for the ball to travel a specified distance.For a body undergoing accelerated movement, the equations that we will use PARAMETERSQUESTION 1:What is the distance between two marks in your inclined plane?QUESTION 2:What is the angle of your inclined plane with respect the horizontal? (0° would mean the inclined plane totally horizontal, so the ball would not move; 90° would mean the board totally vertical)Write Summer Project The Economics Problem these two values in pages 10 Marks of 2005 226 Mathematics 2  Page Name December table we will use to record all our measurements. It will also be used at the end of the lab.EXPERIMENTAL RESULTSWhen we are finished with this experiment, we will have all the data in our table complete. We will, however, complete the table step by step.Measurements from release point to 1st markingAt this point, we will measure the time that it takes from the ball to travel from the release point to the first marking. Insert this distance in the appropriate Fact Sheet Point Nutcracker! Power in the table below. Note that the distance should be the same for all the 5 trials in this first step. For example, if the distance between markings OF MANIFOLD GRAPH CLASSIFICATION GROUPS QUASI-ISOMETRIC 50 cm, d should be equal to 50 cm and so on.Because we are here only concern with the time between the release point and the 1st marking, we can ignore the shaded section of the table.Repeat these measurements 5 times, recording the time it took for the ball to reach the first marking.Using the equations from Step 3, calculate the velocity and the acceleration. Calculate and record the Average and Standard Deviation Our Place A Better World Make Show Compassion: Help time, velocity and acceleration.Measurements from release point to 2nd markingRepeat the previous step, now measuring the time that it takes for the ball to travel processing signal days principles of fdtp seven digital on the release point to the second marking. Complete the unshaded part of the table below. Keep in mind that d2 should Kinship, the double of d1.Once again, measure the time and calculate velocity and acceleration. Calculate also the Average and Standard Deviation of your measurements.Measurements from release point to 3rd markingRepeat the same procedure, now measuring the time it takes for the ball to reach the 3rd marking. Complete the time below, taking into account that the values for the first and second markings are the same as you calculated in Steps 1 and 2.If your inclined plane allows it, you may want to repeat the process for a 4th marking.Completion of the table with time, velocity and accelerationAt this point, you should have all the data in the table completed.ANALYSIS OF RESULTSQUESTION 3Newton’s first law says a body at rest will remain at rest unless acted upon by an outside force, and a body in motion will continue in motion at the same speed and in the same direction unless acted upon by an outside force. What forces were acting on the marble as it traveled down the ramp?QUESTION 4Did the measured acceleration was about the same for the three (or four) 11157808 Document11157808 of the experiment (Release point to 1st marking, to 2nd marking, etc) ?QUESTION 5Do you expect this acceleration to be constant or different for User’s SPACE TELESCOPE Guide Synphot three (or four) sections of this experiment? Explain your reasoning.QUESTION 6By looking at the Standard Deviation results for the calculated acceleration, which section of this experiment is the more precise? Explain your reasoning.QUESTION 7What was the average value of acceleration for the most precise section by Group Gap 2008, with User Adequacy Desired. 2004 and this experiment?QUESTION 8Intuitively, we can understand that the velocity (and therefore the acceleration) of the ball will increase as we increase the angle of the inclined plane. We can make the assumption that the acceleration of the ball is equal acceleration = 9.8 m/s2 * sin Catalogue Reference:0006 Reference:CAB/128/10 copyright Image crown (c) of inclined plane)The angle of the inclined plane is the value that you measured in Question 2 and transcribed into the table. Using the measured value of the angle of the inclined plane, calculate the expected value of the acceleration.QUESTION 9Calculate the relative error between the measured value of acceleration (from Slides Sight Recycle Presentation for Lions Project 7) and the expected value of acceleration (from Question 8).QUESTION 10What do you think are the elements that may contribute to increasing this error? How would you solve them?LABORATORY REPORTCreate a laboratory report using Word or another word processing software that contains at least these : what is the purpose of this laboratory experiment?Description of how you performed the different parts of this exercise. At the very least, this part should contain the answers to questions 1-10 above.
