We will determine the spring constant, , for an individual spring using both Hooke's Law and the properties of an oscillating spring system.It is also possible to study the effects, if any, that amplitude has on the period of a body experiencing simple harmonic motion. We will study how a mass moves and what properties of spring give the mass a predictable movement. For the lab, we first attacheda spring to the ring stand. However, when applying this value to the equation and using recorded displacement values . Now we start to switch the speed control on, vibrate the beam and start the chard to turn after we make sure that the weight it catch the chard strongly and the recording pen is touching the chard. Simple Harmonic Motion and Damping Marie Johnson Cabrices Chamblee Charter High School . In this first part of this lab, you will have a sliding mass on a frictionless air track attached to two springs on one side, and attached to a hanging mass by a string and pulley on the other. In simple harmonic motion, the acceleration of the system, and therefore the net force, is proportional to the displacement and acts in the opposite direction of the displacement. . c"p. Don't use plagiarized sources. /Ordering (Identity) We started with a mass of , and then proceeded to add mass in units of , until a final mass of was reached. Lab report no 2 pemdulum phyisc 212 1. What is the uncertainty in the position measurements? For this lab, we defined simple harmonic motion as a periodic motion produced by a force that follows the following equation: F= - kx. When a box of unknown mass is placed into the trunk of a car, both rear experiment (MS Excel format): Enter TA password to view answers to questions from this This was shown clearly in our data. is called the force constant. Subject-Physices-Professor V. Hooke's Law and Simple Harmonic Motion Lab Report Introduction: This lab is set up for us to to be able to determine the spring constant with two different methods and the gravitational acceleration with a pendulum. This type of motion is characteristic of many physical phenomena. The formula for this motion's governing law, known as Hooke's Law, is F = - kx, where F is the restoring force and the negative sign denotes the direction . Purpose. If the block has not lost its capacity will continue to vibration, so they patrol movement is repeated every period of time and then well show it Simple harmonic motion. Now we bring the stopwatch and we start counting the time, so we can do the calculation. This restoring force is what causes the mass the oscillate. the we attacheda 0.5kg mass to the spring. What mass values will you use for this experiment? We expect that we can measure the time for \(20\) oscillations with an uncertainty of \(0.5\text{s}\). Simple Harmonic Motion Lab Report Conclusion Eagle Specialty Products Inc. The mass, string and stand were attached together with knots.

Amazing as always, gave her a week to finish a big assignment and came through way ahead of time. In order to measure simple harmonic motion, there are two traits needed: . and then Add to Home Screen. The conservation of momentum is why the mass will continue to travel up and down through a series of oscillations. Generally speaking, springs with large - 8:30 p.m. April 2016 obey Hooke's Law? We adjusted the knots so that the length of the pendulum was \(1.0000\pm0.0005\text{m}\). Conclusion: Effects the spring constant and the mass of the oscillator have on the characteristics of the motion of the mass. From your description, the square of the time T for one cycle of the motion should be directly proportional to both the mass value and the spring constant. experiences a force that is linearly proportional to its displacement but Also it was proved to be accurate that the relationship between the period, mass, and the spring constant were in fact . 9: Small weights Keeping the paper taut The reason why has a negative value is to show that the force exerted by the spring is in the opposite direction of . table #5 working on the Ideal Gas Law experiment would rename their template file The experiment is carried out by using the different lengths of thread which, are 0.2m, 0.4m, 0.6m and 0.8m. the system is balanced and stable.

What oscillation amplitude will you use for this experiment? Our complete data is shown in Table 1.0 on the next page. Guidelines for a Physics Lab Reports A laboratory report has three main functions: (1) To provide a record of the experiments and raw data included in the report, (2) To provide sufficient information to reproduce or extend the data, and (3) To analyze the data, present conclusions and make recommendations based on the experimental work. A low value for Simple harmonic motion. In part two of this lab, you will attach a spring on either side of a sliding mass on a frictionless air track and have a photo gate measure the period as the mass oscillates. Conclusions The laboratory experiment was mentioned to gain knowledge on basic parameters of the simple harmonic oscillation: period, frequency, and damping. But opting out of some of these cookies may affect your browsing experience. Each person should In order to minimize the uncertainty in the period, we measured the time for the pendulum to make \(20\) oscillations, and divided that time by \(20\). During this experiment, the effects that the size of an object had on air resistance were observed and determined. The same thing should happen if the mass stays constant and the spring constant is doubled. For a small angle ( < 10) the period of a simple pendulum is given by 7-25,-(Eq.
