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. When a mass is added to the spring it takes the length of, . It will be interesting to understand what gives the mass the oscillating property.It should be a combination of the springs properties and the sheer amout of mass it self. After graphing forces versus displacement, a value of 3.53 N/m was determined as the spring constant. Simple Harmonic Motion and Damping Marie Johnson Cabrices Chamblee Charter High School . when the mass increases the frequency decreases. We repeat this experiment also 2-3 time, after that we start the calculation and the measurement. For example, radiation . We suspect that by using \(20\) oscillations, the pendulum slowed down due to friction, and this resulted in a deviation from simple harmonic motion. To install StudyMoose App tap For our particular study we set up a force sensor which would measure a pulling force in the earthward direction. This sensor was calibrated at 2 point, a zero mass and with a known mass. A pendulum exhibits simple harmonic motion (SHM), which allowed us to measure the gravitational constant by measuring the period of the pendulum. Notice that it is typed and spell checked, and should not contain errors such as interchanging "affect " and "effect". table #5 working on the Ideal Gas Law experiment would rename their template file When a mass is added to the spring it takes the length of . velocity and acceleration all vary sinusoidally. The equation for a pendulum that relates the variables involved is: 2 f =. Simple harmonic motion is the motion of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke's Law. 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. If we assume the two rear A simple pendulum consists of a small-diameter bob and a string with a tiny mass but, enough strength to not to stretch significantly. in the opposite direction, the resulting motion is known as simple harmonic These experiments are suitable for students at an advanced level . Abstract. This type of motion is also called oscillation, motion. 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. Does Hooke's Law apply to an oscillating spring-mass system? The variation of the time period with increasing oscillation was studied for the simple harmonic motion (SHM) and for large angle initial displacements (non-SHM). It was, found that a longer pendulum length would result, in a longer period and that the period of the, pendulum was directly proportional to the square, root of the its length. 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.
