# Using a pendulum to find gravity essay

Development of Dynamics; XXV. The revelations of Greek thought on the nature of the exterior world ended with the "Almagest", which appeared about A. Those of its works that escaped the fires kindled by Mohammedan warriors were subjected to the barren interpretations of Mussulman commentators and like parched seed, awaited the time when Latin Christianity would furnish a favourable soil in which they could once more flourish and bring forth fruit. Hence it is that the time when Ptolemy put the finishing touches to his "Great Mathematical Syntax of Astronomy" seems the most opportune in which to study the field of ancient physics. The velocity time graph is in a straight line, meaning it was going at a constant acceleration. It was heading in a positive direction refer to graph 1.

The relationship between the change in velocity and elapsed time was that the velocity increases constantly as the time increases therefore they were proportionate. The slope of the velocity time graph was accelerating 6.

The velocity position graph refer to graph 2 was curved because changing velocity means change in slope. The change in velocity of an object in free fall was directly proportional to the displacement.

It is directly proportional to the time. This was because as time increases, velocity changed at a constant rate. Due to change in velocity, there was a change in displacement.

Errors After performing the experiment, several errors were noted. One error might be in the calculations in Table 1. The anticipated error was that the numbers would have been rounded and not completely accurate.

A random error that occurred was that one group member released the object not in synchronization with the ticker timer which may have hindered the process of dots being recorded on the tape. Conclusion I concluded that the velocity time graph did go in a straight line. My hypothesis was only partially correct.

Instead of the acceleration being 9.To find the acceleration due to gravity, we will plot the velocity of the mass versus. In this lab you will measure the acceleration due to gravity near the earth's surface with. Purpose: Determine the acceleration due to gravity near the surface of the Earth using a=vf-vi/t.

- calculate the acceleration of gravity for each experiment separately. Then calculate the average result for the whole experiment. After the practical part of this assignment it will be quite useful to write a thematic essay about the accomplished work. Online shopping from a great selection at Books Store.

To determine the acceleration due to gravity using a simple pendulum. Apparatus: Pendulum, meter scale, stand, stop watch, vernier callipers. Procedure: 1. The diameter of the bob is determined by using vernier callipers and then its radius (r) is calculated.

2. Find the length of the pendulum l using . Unlike steps 3 and 4, you'll want to include this step every time you use your pendulum to answer a question or set of questions. The purpose is to establish where the pendulum will get its answers. The goal is to tap into your higher self. Practical Exam Laws of Pendulum – Viva Voice Question With Answer For: Science Class 11 | Physics.
