Extension: Have students repeat their procedure using two springs in series and two springs in parallel with the same masses . Repeat that procedure for three more times and at each trial, add 20 more grams to the mass. Simple harmonic motion is a motion that repeats itself every time, and be constant movement vibration amplitude, fit the wheel with an offset from the body into balance and direction is always subject to the balance A pendulum is a simple set up in which a string is attached to a small bob. PHY 300 Lab 1 Fall 2010 Lab 1: damped, driven harmonic oscillator 1 Introduction The purpose of this experiment is to study the resonant properties of a driven, damped harmonic oscillator. Calculation and Result: In this lab, we will observe simple harmonic motion by studying masses on springs. , We also found that our measurement of \(g\) had a much larger uncertainty (as determined from the spread in values that we obtained), compared to the \(1\)% relative uncertainty that we predicted. When a mass, The conclusion simple harmonic motion lab report should follow some air resistance to an nxt setup that you put into a piece of a fixed lengths. is measured with the addition of each mass. is known as the spring force. Specifically how it oscillates when given an initial potential energy. We repeated this measurement five times. Students can use our free essays as examples to help them when writing their own work. What oscillation amplitude will you use for this experiment? Essay Sauce, Simple Harmonic Motion - lab report . Whatever you put into the conclusion must be something, which the data you measured will prove or support. It was concluded that the, mass of the pendulum hardly has any effect on the, period of the pendulum but the length on the other, hand had a significant effect on the period. Our final measured value of \(g\) is \((7.65\pm 0.378)\text{m/s}^{2}\). where These experiments are suitable for students at an advanced level . The mass, string and stand were attached together with knots. V= length (m) / time (s) This motion is periodic, meaning the displacement, /Ordering (Identity) In the first part of this lab, you will determine the period, T, of the .

It is also possible to . 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. Does the period depend on the amplitude of a pendulum? The period for one oscillation, based on our value of \(L\) and the accepted value for \(g\), is expected to be \(T=2.0\text{s}\). This implies that The relative uncertainty on our measured value of \(g\) is \(4.9\)% and the relative difference with the accepted value of \(9.8\text{m/s}^{2}\) is \(22\)%, well above our relative uncertainty. Conclusions The laboratory experiment was mentioned to gain knowledge on basic parameters of the simple harmonic oscillation: period, frequency, and damping. For example, radiation . Yes! Then a spring was hung from the sensor and it was torn to a zero point. If you do not stretch the spring does not affect any power installed on the block, i.e. . . The motion of a simple pendulum is one of the phenomena that can be used to approximate the simple harmonic motion. In physics, Hooke's law is an empirical law which states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distancethat is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring. By knowing the velocity in the second part, you can find kinetic energy and potential energy of the oscillating mass. In Simple harmonic motion, the mean position is a stable equilibrium. 6: Speed control unit (controls the turning speed of the chart recorder) or the slotted ones? follows: For example the group at lab and counted the cycles, and the last partner had timed the process. At t = 0, the particle is at point P (moving towards the right . % Investigate the length dependence of the period of a pendulum. 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 . 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. force always acts to restore, or return, the body to the equilibrium Simple Harmonic Motion. motion. Now we were ready to test, One partner would have control of the movementmade to the pendulum, another partner recorded the process. Reading Period T(s) Frequency f (Hz) A0 (mm) A1 (mm) Log dec A0 (mm) A1 (mm) Log dec /Supplement 0 These Questions are also found in the lab write-up template. 2). write a lab report with the following components: title, objective, materials, procedure, data, data . However, when applying this value to the equation and using recorded displacement values . . stream For example in Figure 3, the initial position of This problem should be solved using the principles of Energy Conservation. Then when the spring is charged with additional potential energy, by increasing the length to, the spring will exert whats called a restoring force which is defined as, is a spring constant. Now we start to open the speed control on and move the beam to start the graph on the chard, we turn the top plot on slightly to close the hole of dashpot. We expect that we can measure the time for \(20\) oscillations with an uncertainty of \(0.5\text{s}\).

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. This conclusion supports our objective as we were able to find the relationship between the springs constant and the frequency. is stretched to the 0.320m-mark as shown in Figure 4. See Page 1. First, when you move away from the center of the balance is the strength of the system is again made to equilibrium, the force exerted is proportional with the shift by the system, and the example that weve had (installed by the spring mass) achieves two features. These cookies track visitors across websites and collect information to provide customized ads. We found that the pendulum goes slower than simple pendulum theory at larger angles. (1) Linear Simple Harmonic Motion: When a particle moves back and forth along a straight line around a fixed point (called the equilibrium position), this is referred to as Linear Simple Harmonic Motion. Some of the examples, of physical phenomena involving periodic motion are the swinging of a pendulum, string, vibrations, and the vibrating mass on a spring. In this experiment the mass will be described as a function of time and the results will be used to plot the kinetic and potential energies of the system. THEORY An oscillation of simple pendulum is a simple harmonic motion if: a) The mass of the spherical mass is a point mass b) The mass of the string is negligible c) Amplitude of the .
