An analysis of experiments and theories in measuring acceleration

Kim Submitted on 25 Jan It is known that Einstein's conceptual base for his theory of relativity was the philosophy formulated by Immanuel Kant. Things appear differently to observers in different frames.

But if you are only interested in equations, skip to the end. There are plenty of hard numbers and lovely equations there, of a sort to satisfy and shock all but the most jaded.

But I don't recommend it. The lead-in is not only necessary, it is a great deal of fun, I am told. Critics of my papers often lead with the argument that famous experiments like this have been repeated thousands of times by professionals and amateurs alike, some of them very smart people.

This argument is supposed to imply a sort of statistical power or infallibility by numbers, I suppose.

But it should be clear by now that arguments of that sort are astronomically weak. In fact, all people are wrong about most things all the time. So it should be no surprise to find that most of what we claim to know is false, or at best incomplete.

It should also not surprise us that the smartest people are wrong almost as often as the dullest. Being what we are and where we are, historically, it just so happens that even our brightest people are not that bright. Due to its rarity, every good idea comes as a shock to everyone, even the one who thinks it.

I daresay it would surprise no one if an alien landed and told us that Newton and Einstein and Cavendish and Feynman were wrong about most everything. We would expect it, really. When it gets right down to it, we know in our heart of hearts that civilization here on earth is in its infancy.

We must be aware that technology is only a few centuries old, at most at least in its current incarnationand that the majority of our hypotheses are but skeletons.

In private moments we are forced to admit to ourselves that gravity, among many other things, is still a great mystery. We see scientists in other centuries overthrowing ridiculous dogma and we cheer them, but we do not welcome the overthrow of our own dogma.

We can accept the new ideas of dead scientists, since the newness is long gone, but we cannot accept new ideas that are new now. I am nothing but someone who has ideas and the temerity to post them. The Cavendish experiment is routinely included in a short list of the greatest or most elegant experiments ever done.

Like all of the other existing dogma, it has surrounded itself with a nearly impenetrable slag heap of boasting and idolatry, most if not all of it sloppy and unanalyzed. This was true even before the internet arose, but now it is true to the nth degree.

Like everything else, the Cavendish experiment has added to its armor a thousand Wikipedia-like entries and glosses by a thousand mid-level physics professors.Physics General Physics I Lab Columbia University Department of Physics Fall Contents and guide you in completing your analysis and write-up.

In physics there are a few interesting experiments to measure acceleration. By combining these practical techniques with a simple equation involving the speed of an object moving and the time it takes that object to travel a specified distance, acceleration can be calculated.

Centripetal Force Experiment: Lab Analysis

THEORY The purpose of this experiment is to measure the acceleration of a freely falling object. The mathematician and physicist Galileo Galilei defined the concept of acceleration, the rate of change of velocity with respect to time. He also performed experiments with spheres rolling down inclined planes.

The model represents the important aspects of slip motions and suggested that an abrupt change in the acceleration force from positive to negative magnitudes was .
