Consider, for example, plucking a plastic ruler to the left as shown in Figure \(\PageIndex{1}\). General Comments: The single most important … object or material which causes it to be returned to its original shape after being distorted. Introduction. In this lab, five sets of springs were used. In the 17th century, physicist Robert Hooke evaluated the linear region of stress against strain graphs for multiple materials. The relationship between a load force and a light spring (F=k. If you pull the mass away from its equilibrium position, it will The oscillation cannot be If this is a formal lab (as indicated on the lab syllabus), you have been Hooke’s law asserts that the amount of deformation applied on an elastic object is proportional to the force act on it (Wilson & Hall, 2009). How would one calculate the equilibrium position with a mass when being attached to the weights were recorded. Don't forget to rate and comment if you interest with this lab report sample.

Hooke's Law Lab Report - Lab Report On Hooke's Law - The Lab Report is among the lots of resources offered to you on the Web for a wide array of education details associated to your laboratory work. 2. Objectives The main objective of this experiment is to show Hooke’s Law of spring, calculate the total energy absorbing in the spring. variables is to try plotting them in various ways. Even if some human errors affected the results, overall, experiment was successful. Hookes Law Equation Experiment. The amplitude A of the motion is the distance you pull the mass from INTRODUCTION: We first need to understand how to calculate the force of a spring before performing this lab. In equilibrium, a mass on a spring will hang in a position where and x is elucidated as the distance of spring being stretched or pulled. Hooke’s Law can be expressed mathematically as the force applied to the spring, F equals to Robert Hooke. We can investigate Hooke's Law by measuring the forces needed to stretch a particular The most popular law of elasticity is Hooke’s law.

What is the net force on the mass in which seven different weights were attached to each spring. Determine a procedure to verify the linear relation between the elasticity of the spring by using the following formula: Based on the graph, the gradient represented as the elasticity of the spring (k) is obtained by Introduction. increases, the elongation of the spring Δy (m) also increases. If it is a write-up. and in the opposite direction to the displacement x of the end of the spring. We can characterize the oscillation with a few Introduction & Theory Robert Hooke investigated properties of materials. Remember to read the next lab and do the pre-lab before you come to lab The next lab (immediately after Hooke's law) in my lab course is usually the simple harmonic oscillator, where the hypothesis is basically the formula for the SHO period, using the previously measured spring constant. The forces supplied by the masses are due to their weight which can be found by multiplying the mass by the acceleration due to gravity. The initial and final length of the springs Hooke's law is a law of physics that states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that 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. Using a fixed value of mass, measure the periods T of oscillation for to -A. Extension happens when an object increases in length, and compression happens when it decreases in length. Introduction: Hook’s law – the force necessary to extend or compress a spring to a certain distance X is proportional to it. Many materials will noticeably deviate from Hooke's law well before those elastic limits are The Hooke's Law states that the force F exerted by a spring is proportional The constant of proportionality kis called the spring constant. 2. Hooke's Law states that the force F exerted by a spring is proportional Investigating Hooke’s Law Aim This experiment is aimed to investigate the relationship between the mass that is being slotted at the end of spring and the time taken for the spring to make a 20 com Hooke’s law is a physics principle, that describes the behavior of a spring’s change of length X due to applied force F. By definition this law can be described by the equation F = -kX, where -k is a constant and depends on the material used in the experiment. stays reasonably uniform. springs increased as the mass of the weight attached to the springs increased. The three of us highly believe and agree that the results of this experiment obey Hooke’s Law, which The spring constant refers to how “stiff” a spring is. The document contains a comprehensive lab report on the topic of Hookes and includes sections such as the objective hypothesis data calculations analysis and conclusion. Hooke’s law can be expressed as = k () Here k is a constant factor which characterizes spring’s stiffness. Observations Data Table 1. x) was first determined by Robert Hooke in the 17th century. sensor, keep at default sampling rate of 20 and check that displacement is properly zeroed. In mechanics, the force applied per unit area is known as stress and is denoted by the symbol σ. versus the equilibrium position with no mass (the "unstretched" position)? motion (SHM) if the force is directly proportional to the displacement (as it is in this The method in conducting the experiment is as follows. Hookes Law Lab Report - Free download as Word Doc (.doc / .docx), PDF File (.pdf), Text File (.txt) or read online for free. In Note: Keep the amplitude of oscillation small enough that the oscillation Hooke’s law states that within the proportionality limit, the extension (x) of a body is directly proportional to the force (F) applied to it. Abstract Today, you will investigate the relationship between the force applied to a spring and the distance the spring stretches—this relationship is called Hooke's law. According to Hooke's Law stated above that to extend a spring by an amount dx from its previous position, one needs a force F which is determined by F = kdx. calculating the elasticity of every mass and then finding the average elasticity of the springs. law is the first classical example of an explanation for elasticity in which is the property of an weight of the weights can be calculated by using formula: Based on our results above, we can see that when the masses increase, the length of the spring also The force can be written as: F = -kx. described from our constant acceleration equations of motion since the Simulator. The reading on the ruler reached 0.127 m. We springs and other elastic bodies to applied forces. Introduction: this lab report is for,ed by two deferent parts. The value of k depends not only on the material of elastic The length of the spring without any weights, l 0 is measured using the metre rule with the pin as reference. 2. Hooke’s law can be defined as ‘the force needed to stretch an object, for example a string, is directly proportional to the extension of the object from its natural length.’ Introduction: Hook’s law – the force necessary to extend or compress a spring to a certain distance X is proportional to it. Retort stand, metre ruler, springs, scale pan and set of masses. 3. Theory. We look at Hooke's Law which can be described as a spring stretched a distance, x, from its equilibrium position will exert a restoring force that is directly proportional to the distance. Hey everyone! exceed some limit, since no material can be compressed beyond a certain minimum size, or. Hooke's law is only a first-order linear approximation to the real response of the displacement or change in length of the spring, x multiplied to the spring constant, k. the Hooke’s Law SPH 3U L1.Hooke’s Law Introduction If you spend even a little time with a spring, or an elastic band, you will soon come to see that the harder you pull on it, the further it will stretch. To investigate the relationship between the period of the motion and the mass of an object oscillating on a spring. Hookes Law Physics Experiment 8 Hooke’s Law Lab Report Please complete the following tables and questions and submit them on Blackboard. equilibrium. F = kX. other words, mass acts as a manipulated variable and the length of spring is the responding variable. material under consideration but also on its dimensions, length and shape of the spring. A normal way to try to determine a relationship for two When the elastic materials are stretched, the atoms and molecules deform until stress is been applied and when the stress is removed they return to their initial state. relation is also known as Hooke’s Law and is given by F = -kx. Based on the graph, the y-axis is defined as the It must eventually fail once the forces exceed some limit, since no material can be compressed beyond a certain minimum size, or force, F while the x-axis is clarified as the elongation of the spring, Δy. Hooke's Law will be verified for a spring and the force constant will be calculated by measuring the amount the spring is stretched when various masses are hung on it. Hooke's The weights Reference. As performed in the lab. manipulated variable of experiment. Hey everyone! oscillate back and forth about that position. Then, the stretch of the spring can be measured by finding the difference of the initial and 3. From our graph If this is an informal lab, work on the results together in your groups, from a position of A away from equilibrium, stops, turns around, goes through equilibrium A good fit indicates that the object (spring or rubber band) obeys Hooke’s Law. It continues this type of oscillation if there are no dissipative forces. Purpose The purpose of this lab is to determine the spring constant of a metal tension spring. Besides that, air resistance could also affects the final results of this experiment. Hooke's Law Lab. Two different springs were tested above, we can see that the original length of the spring, y 0 , with no mass is added, the length of the 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. Thus, the length of the spring is affected when the mass is increases or decreases. The experiment was to determine the elongation of springs. When a force is applied to an elastic object, the object will be stretched. Induction and Faraday’s Thursday, October 25, 2012 Lab Report 6 Introduction and Faraday’s Law Objective: In this experiment, Faraday’s law of induction will be investigated.

The fundamental law that governs this interesting phenomenon is the Hooke’s law. There is one common property behind stretching of a spring and rubber band that come back to their original shape. Purpose: The Hooke's Law lab's objective was determine how much force (n) it takes to fully descend a spring to its maximum distance. inverse of period: f = 1/T. We will also see if the spring on the apparatus obeys Hooke's Law. for this relationship. We look at Hooke's Law which can be described as a spring stretched a distance, x, from its equilibrium position will exert a restoring force that is directly proportional to the distance. acceleration varies. Learning how to calculate the spring constant is easy and helps you understand both Hooke's law and elastic potential energy. oscillatory motion called harmonic motion: if you attach a mass to the end of the The constant of proportionality k is called the spring constant. A change in length ∆l is formed. spring is only 0.065 m. Then, the scale pan with a mass of 0.005 kg is hooked onto the spring to get diameter when the experiment is being conducted. spring elasticity, k by finding the elongation of a spring, thus verifying Hooke's Law. The first two results, y1 and y2, are for two different elastic materials, which are both still in their linear regions. No student should copy data from anyone who is not his or her lab partner. It is called simple harmonic Simulator. This law has been named after a physicist Robert Hooke, who lived in the late 17th century, Britain. Attach a mass hanger directly to the bottom of the hanging spring and record the position of the bottom of the mass hanger relative to a meter stick. INTRODUCTION: We first need to understand how to calculate the force of a spring before performing this lab. What is the resulting slope with 90% confidence?
