What is the purpose of the pendulum lab?
The purpose of this lab is to prove mass has no affect on the period of a pendulum only the length of the pendulum affects the period of the pendulum. This lab will also analyze the Mechanical Energy of the pendulum in a Closed System.
How do you write an abstract for a lab report in physics?
The abstract is a short summary of the main ideas found in the lab report. It should include 1) the purpose of the study or the question being addressed by the study, 2) the procedures used in the study, 3) the major results of the study, and 4) any conclusions drawn by the author(s).
What is the conclusion of simple pendulum experiment?
The surprising conclusion – the pendulum traverses a longer distance in a shorter time, than in a shorter distance, and its period is shorter. There are a number of reasons why Galileo thought that the period remains constant. One factor which Galileo failed to consider is friction.
What is the theory of simple pendulum experiment?
A simple pendulum consists of a mass m hanging from a string of length L and fixed at a pivot point P. When displaced to an initial angle and released, the pendulum will swing back and forth with periodic motion. with being the natural frequency of the motion. …
What factors affect the period of a pendulum?
The mass and angle are the only factors that affect the period of a pendulum. b. The mass, the angle and the length are the three variables affecting the period.
Are lab reports APA or MLA?
As a complete style and guideline for writing, the APA is a valuable tool for writing scientific papers, laboratory reports, and papers covering topics in the field of psychology, education, and other social sciences. The APA style allows for in-text citations, direct quotations, and endnotes and footnotes.
How can you improve simple pendulum experiment?
Improve the accuracy of a measurement of periodic time by:
- making timings by sighting the bob past a fixed reference point (called a fiducial point )
- sighting the bob as it moves fastest past a reference point. The pendulum swings fastest at its lowest point and slowest at the top of each swing.
What are the three laws of simple pendulum?
The Laws of a Simple Pendulum
- 1st law or the law of isochronism: The time period of the simple pendulum is independent of the amplitude, provided the amplitude is sufficiently small.
- 2nd law or the law of length:
- 3rd law or the law of acceleration:
- 4th law or the law of mass:
What happens if you add more weight to a pendulum?
When you add a weight to the bottom of the pendulum on the right, you make it heavier. When you add a weight to the middle of the other pendulum, however, you effectively make it shorter. Shorter pendulums swing faster than longer ones do, so the pendulum on the left swings faster than the pendulum on the right.
What is the simple pendulum lab?
PHYSICS LABORATORY: The Simple Pendulum The purpose of this lab was to experimentally determine a value for g, the acceleration of Earth’s gravity, by using the given ‘pendulum equation’ and experimental data for the period of a pendulum and the length of a pendulum string.
What was the goal of the pendulum experiment?
This goal of this experiment was to determine an experimental value for g using the simple pendulum equation and measuring the period against varying lengths of string. The mass at the end of the string was held constant at 200 g.
Does length affect the period of a simple pendulum?
In regards to the length experiment, the graph below shows the period as a function of the length with a correlation coefficient of .99, which is strong. The graph takes this shape because it has been linearized- that is, the T values have been squared. It is apparent that length does affect the period of a simple pendulum.
What is the value of G in the pendulum experiment?
This goal of this experiment was to determine an experimental value for g using the simple pendulum equation and measuring the period against varying lengths of string. The mass at the end of the string was held constant at 200 g. From the graph of T2against l, the final experimental value of g was found to be 9.99 ±0.38 ms-2″.
