Investigating Hooke’s Law. Aim. Hooke’s Law 1. Hooke's Law Elastic force occurs in the spring when the spring is being stretched/compressed or deformed (Δ x) by the external force.
In equation form, we write.
It tries to bring the deformed end of the spring to the original (equilibrium) position. Hooke's Law Elastic force occurs in the spring when the spring is being stretched/compressed or deformed (Δ x) by the external force. Purpose: The primary purpose of the lab is to study Hooke’s Law and simple harmonic motion by studying the behavior of a mass on a spring. where x is the size of the displacement. 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. The process which has been used above has calibrated the spring. See Fig. It tries to bring the deformed end of the spring to the original (equilibrium) position. (Engineers say "Stress is proportional to strain".) Purpose: The primary purpose of the lab is to study Hooke’s Law and simple harmonic motion by studying the behavior of a mass on a spring. Foundation for seismology, acoustics and molecular mechanics. As the mass of the end of the spring increases, the time period for the spring to complete 20 oscillation will also increase. 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, =, 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. The transparent scale can be moved vertically to align zero with the brightly colored stretch indicator. It is a unique property of this Newton spring balance since all springs have a unique spring constant. If you're behind a web filter, please make sure that the domains … Hooke’s law can be investigated by measuring how much a string stretches from a known applied force. behavior follows Hooke's law to within the limits of accuracy of the experiment. Theory The shape of a body will distort when a force is applied to it. 2. Hooke’s Law FAQs . Hypothesis. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab … Version 42-0264-00-01 Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. Hooke's law is the first classical example of an explanation of elasticity – which is the property of an object or material which causes it to be restored to its original shape after distortion.
If Hooke's Law is correct, then, the graph of force versus stretch will be a … Hooke’s Law experiment “I am aware of the requirements of good academic practice and the potential penalties for any breaches” Computer Applications: Assignment 1. If you're seeing this message, it means we're having trouble loading external resources on our website. The applications of Hooke’s Law are as follows: Hooke’s Law is used all branches of science and engineering; It is used as a fundamental principle behind manometer, spring scale, balance wheel of the clock. Hooke's Law says that the stretch of a spring is directly proportional to the applied force. Elastic force acts in the opposite direction of the external force. 2. The proportionality constant k is specific for each spring.. phy 113: hooke’s law/springs objective: the objective of this lab was to test hooke’s law by measuring the spring constants of different springs and spring EXPERIMENT 4 HOOKE’S LAW 1. Hooke's Law states that the restoring force of a spring is directly proportional to a small displacement. A formal lab report should include a title page like this one, with all of the appropriate information -- a descriptive title, your name, the course title, the date, and an abstract. Checkpoint: Be sure to have your TA sign your lab worksheet, printed Inlab, and all printed graphs after each part is completed. In symbols, F = kx, where F is the force, x is the stretch, and k is a constant of proportionality. 2. Objectives The main objective of this experiment is to show Hooke’s Law of spring, calculate the total energy absorbing in the spring.

See Fig. 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.
