Ynzon and Rachel Pauline E. Print out a few representative graphs to be included with your laboratory report. Introduction A pendulum is an object, hung from a fixed point, that swings freely back and forth under the action of gravity. They are the slope of the line of the graph of T² against L, and the gravity of the pendulum motion. It should also be noted, that for all our measurements, we used a constant, and small, angle of maximum displacement a.
Damping always occurs when there is. In gathering the experimental data there will be a degree of uncertainty associated with the. Pendulum is usually employed in the student laboratory. There are four kind of distillation: simple distillation… 1429 Words 6 Pages Youssef Elseifi Mr. Your volunteer should start the stopwatch as soon as you let go. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot.
In my lab report for the Density Lab I recorded the steps to the lab. If the phone twists or wobbles a lot as it swings back and forth, this will affect your data. Rinse with D-water Apply Iodine Mordant for 1 minute. Hypothesis: The length of the string has an effect on the time it takes for the pendulum to swing back and forth. Option 1: Using the Google Science Journal App Science Journal is an app that lets you record data using sensors that are built into many smartphones, including an accelerometer which measures motion.
Determination of a spring constant and observation of the period of an object in simple. Procedure a Show a demonstration pendulum and ask students to think about the variables that may affect the time period for one oscillation. Physics 211 Experiment 12 Simple Harmonic Motion Experiment. Does mass affect the speed of the swing or how long the pendulum swings? You could extend this timeline by describing further developments in timing devices, right up to the atomic clock usually containing caesium which is accurate to within 10 -9 seconds per day. When a pendulum is displaced from its resting equilibrium position, it is subject to a restoring. For example, the peaks in Figure 4 occur at 5.
The Pendulum Experiment is an experiment about gravity. Then you can start testing the affect of change when the angle of release changes. Notes entered on these pages will be needed when you write your lab report and as. They also help all students better understand their physical world and how it works in their everyday lives, as well as how to become better citizens by understanding the process of scientific research. After the end of the period or to take your report home to complete it. Repeat the experiment, running three trials with the bob drawn back 7.
In essence, this is an experiment designed for you to use your knowledge of data analysis the mean, standard deviation. In order to reduce possible random errors in the time measurements, we repeated the measurement of the period three times for each of the ten lengths. The introductory discussion can put the pendulum into a scientific and historical context by describing the development of timing devices. First of all, we need to find the average of the three trials, which will reduce our error, stated in the header. This occurs because the pendulum moves back and forth first in one direction, then the other for one complete period; giving two peaks in the Y acceleration graph per swing of the pendulum's motion. Its periodic motion is defined by an acceleration that is proportional to its displacement and directed awards the centre of motion. To do this, check out The California Academy of Sciences resource.
If we suspend a mass at the end of a piece of string, we have a simple pendulum. In this experiment the acceleration due to gravity g is determined using two different methods. Try one of our science activities for quick, anytime science explorations. Print out a few representative graphs to be included with your laboratory report. The swing is supported by chains that are attached to fixed points at the top of the swing set.
The purpose of this experiment is to measure the acceleration due to gravity by. These back and forth movements are called oscillations. In this lab you will attempt to measure the acceleration of gravity g at the surface of. This line may indicate that more readings are needed as the plotted points may be too close together.

However, pendulums were being used for centuries before this. Their task is to test the hypothesis, by collecting and analysing data. Scientific Method — Simple Pendulum 15. The most widespread applications of the simple pendulum are for timekeeping, gravimetry the existence of the variable g in the period equation of simple pendulum - - means that the pendulum frequency is different at different places on Earth , seismology, scholar tuning, and coupled pendula. Hypothesis As the length, mass and angle of release change, the period T will change for each one of these factors.
