EXPERIMENT 2 Measurement of g: Use of a simple pendulum OBJECTIVE: To measure the acceleration due to gravity using a simple pendulum. Textbook reference: pp10-15 INTRODUCTION: Many things in nature wiggle in a periodic fashion. That is‚ they vibrate. One such example is a simple pendulum. If we suspend a mass at the end of a piece of string‚ we have a simple pendulum. Here‚ the to and fro motion represents a periodic motion used in times past to control the motion of grandfather and cuckoo clocks

Introduction: Aim: To find the relationship between the length of a simple pendulum and the period of oscillation. Research question: How does the string length of the pendulum affect the period of oscillation? Prediction: The longer the string‚ the longer it will take to make one complete oscillation. Variables: Independent variable: Length (L). Dependent variable: Period of oscillation (T). Controlled variable: Mass of the plasticine. Tools & Materials: Stopwatch. Ruler. String. Plasticine

Name(s)_____________________ HOOKE’S LAW and SIMPLE HARMONIC MOTION INTRODUCTION Any motion that repeats itself in equal intervals of time is called periodic motion. A special form of periodic motion is called Simple Harmonic Motion (SHM). Simple Harmonic Motion is defined as oscillatory motion in which the resultant force on the oscillating body at any instant is directly proportional to its displacement from the rest position and opposite in direction to its motion. For a spring system‚ this can

Matthew Mannetta Simple Harmonic Motion Lab Report Introduction 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. In this lab‚ we will observe simple harmonic motion by studying masses on springs. In the first part of this lab‚ you will determine the period‚ T‚ of the spring by observing one sliding mass that is attached to two springs with the spring constant k‚ and attached to a hanging mass by a string

Simple Harmonic Motion By Panun Bali Aim: The aim of this experiment was to determine the spring constant “k” of a spring using Hooke’s Law and Simple Harmonic Motion. Theory: Part 1: We know from the theory that the Time Period “T” for any spring that undergoes simple harmonic motion: T = 2π * √ (m/k) Where “T” is the Time Period of the spring; “m” is the mass attached to the spring and “k” is the spring constant of the spring used. After mathematically manipulating the equation

and x changes proportionally to g. What connects the motion of both the spring and the pendulum? They are connected by the fact that they both move with simple harmonic motion (SHM)‚ which is the most common form of motion‚ as it is related to circular motion‚ and also to the motion of pendula‚ springs‚ logs in th water‚ water in a u-tube‚ pulsars‚ vibrating molecules‚ etc. What is simple harmonic motion? it is motion in which: 1. The motion (and the acceleration) is directed towards a fixed point

Simple Harmonic Motion Objective The purpose of this experiment was to investigate the different variables describing simple harmonic motion (SHM) using a spring-mass system in vertical oscillation. We measured the position and velocity of the spring-mass system under different conditions in order to extract parameters used to describe SHM such as amplitude‚ frequency‚ and phase. We tested whether the predicted behaviour based on our mathematical model of SHM was cohesive with the observed parameters

Objectives The main objective of this experiment was to determine the spring constant using the dynamic method. 2. Theoretical fundamentals On the one hand‚ when a spring oscillates‚ the movement which describes can be classify as a simple harmonic motion.
