The baseball is released. Purpose. displayed in the table below. This sensor was set to a frequency of. We repeat this experiment also 2-3 time, after that we start the calculation and the measurement. The data correlate close to Hooke's Law, but not quite. V. Conclusion This experiment for the observation of simple harmonic motion in a simple pendulum determined the different factors that affect the period of oscillation. (download the rest of the essay above). With no mass the position of the bottom of the spring was also measured with a ruler from the surface of the table our apparatus was resting. Simple Harmonic Motion Lab Report. c"p. 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. A pendulum exhibits simple harmonic motion (SHM), which allowed us to measure the gravitational constant by measuring the period of the pendulum. oscillating body and the spring constant, Report, Pages 2 (368 words) Views. Each lab group should What oscillation amplitude will you use for this experiment? 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 This period is defined as where, . In this lab, we will observe simple harmonic motion by studying masses on springs. Thus, by measuring the period of a pendulum as well as its length, we can determine the value of \(g\): \[\begin{aligned} g=\frac{4\pi^{2}L}{T^{2}}\end{aligned}\] We assumed that the frequency and period of the pendulum depend on the length of the pendulum string, rather than the angle from which it was dropped. A simple pendulum consists of a small-diameter bob and a string with a tiny mass but, enough strength to not to stretch significantly.

We recorded these oscillations with data studio for about 10 seconds. 04/20/12. table #5 working on the Ideal Gas Law experiment would rename their template file Once such physical system where . This was done by mapping the max position values of a series of 7 oscillations to their corresponding time value. We can then determine the spring constant for this spring: where The time it takes for a mass to go through an entire oscillation is what is known as a period, a the period of a mass on a spring is dependent of two variables. Lab report no 2 pemdulum phyisc 212 1. A low value for The recorded data is They also happen in musical instruments making very pure musical notes, and so they are called 'simple harmonic motion', or S.H.M. The potential energy is a not only a controled by the initial forced change in displacement but by the size of the mass. Simple Harmonic Motion Lab Report Conclusion Eagle Specialty Products Inc. If the mass of the component is 10g, what must the value velocity and acceleration all vary sinusoidally. where frequency f the inverse of period T, f = 1 T. Therefore: 2 T = where I = (1/3)mr, so 2 T = . , This was the most accurate experiment all semester. position regardless of the direction of the displacement, as shown in Specifically how it oscillates when given an initial potential energy. Dont know where to start? In this lab we will study three oscillating systems that exhibit nearly ideal simple harmonic motion. The brightest students know that the best way to learn is by example! The uncertainty is given by half of the smallest division of the ruler that we used. force always acts to restore, or return, the body to the equilibrium Also it was proved to be accurate that the relationship between the period, mass, and the spring constant were in fact, . We do NOT offer any paid services - please don't ask! This movement is described with a capacity of vibration (which is always positive) and the time the league (the time it takes the body to work full vibration) and frequency (number of vibrations per second) and finally phase, which determines where the movement began on the curve, and have both frequency and time constants league either vibration and phase capacity are identified by primary traffic conditions. Our final measured value of \(g\) is \((7.65\pm 0.378)\text{m/s}^{2}\). When a box of unknown mass is placed into the trunk of a car, both rear This correspond to a relative difference of \(22\)% with the accepted value (\(9.8\text{m/s}^{2}\)), and our result is not consistent with the accepted value. The next part, you will determine the period, T, of oscillation caused by two springs attached to either side of a sliding mass. The mass, string and stand were attached together with knots. . The following data for each trial and corresponding value of \(g\) are shown in the table below. and then Add to Home Screen. The cookie is used to store the user consent for the cookies in the category "Other. All of our measured values were systematically lower than expected, as our measured periods were all systematically higher than the \(2.0\text{s}\) that we expected from our prediction. What mass values will you use for this experiment? follows: For example the group at lab What is the uncertainty in the mass measurements? Mass is added to a vertically hanging rubber band and the displacement Another variable we care about is gravity g, and then we are able to change the equation from T to g as follows: =2 (Equation 1) . static and dynamic situations. 692. Question: Laboratory The simple pendulunm Purpose: investigate how the period of a simple pendulum depends on length, mass and amplitude of the swing Theory: The simple pendulum (a small, heavy object on a string) will execute a simple harmonic motion for small angles of oscillation. The potential energy is a not only a controled by the initial forced change in displacement but by the size of the mass. What is the uncertainty in the position measurements?
