FUNCTIONS EXPERIMENT PENDULUM Introduction For a pendulum swinging back and forth, the amount of time required to complete one full swing is called the period.
It can be shown that the period T of the swinging pendulum is proportional to the square root of the length l of the pendulum: T = 4π 2 Lab M1: The Simple Pendulum Introduction. It is an example of simple harmonic motion and it occurs as a result of swing a bob of the pendulum; the bob goes forth and back. Textbook reference: pp10-15 INTRODUCTION: Many things in nature wiggle in a periodic fashion.
In fact, the period and the length of the pendulum are related by a power function. Galileo discovered that the period depends only on the length of the pendulum and the acceleration due to gravity. Physics report Simple pendulum 1.j 2013/14 Hanne Martine G. Rstad Side 1 av 4 Simple Pendulum Investigation of gravity and restori ng force Aim To determine acceleration due to gravity by measuring the time period of a simple pendulum. A pendulum is considered to be a simple harmonic motion. For this lab we are trying to verify that gravity on earth is 9.81, using a simple pendulum. // The period of pendulum is affected by the length of the thread. 1: Free body diagram of simple pendulum motion. The pendulum method is used for determination of the acceleration of gravity (g).
// The period of pendulum … The Simple Pendulum Laboratory Report Abstract.
Simple Pendulum Lab Report Introduction Paper The relationship between the length and the time for one swing (the period) has been researched for many centuries, and has allowed famous physicists like Isaac Newton and Galileo Galilee to obtain an accurate value for the gravitational acceleration ‘g. Introduction Oscillation of a pendulum is a result of acceleration due to the gravity.
Our experiment may be similar to one you have done in high school, however, the mathematical analysis will be more sophisticated. A simple pendulum performs simple harmonic motion, i.e. A pendulum is considered to be a simple harmonic motion.
The simple pendulum provides a way to repeatedly measure the value of g. The equation of motion from the free body diagram in Figure 1: FIG. Experimental Set-Up. Determining the Acceleration Due to Gravity with a Simple Pendulum (Your name) Advanced Undergraduate Lab, Department of Physics and Astronomy, University of Utah, Salt Lake City, Utah 84112 This is an example of a lab report associated with obtaining the acceleration due to gravity (g) and applying mathematical models.

F= ma= mgsin (2) can be written in di erential form g L = 0 (3) If we suspend a mass at the end of a piece of string, we have a simple pendulum. When the bob comes back to its starting point, it completes one oscillation.
When pulled back and released, the mass swings through its equilibrium (center) point to a point equal in height to the release point, and back to the original release point over the same satisfied and the motion of a simple pendulum will be simple harmonic motion, and Equation (2) can be used.
