Addendum to Coriolis Force; Definition of Centripetal Force. 2

We need to understand first that Force can be categorized into two types. One is called tangential or collinear force. This component of the force is always along the direction of motion and changes speed of an object. It can change direction once the velocity of the object has become zero. Its NOT centripetal force. It can never make an object go in a plane or 3 D trajectory, as the motion is limited to only one dimension. The object can only go back and forth.

Now look at the other component. Its called a radial force. Its always perpendicular to the direction of motion. This force is called centripetal force, always. Note that its different from what we call central forces.

In consequence, both tangential and radial forces can be central. More…

An interesting problem in elementary mechanics. Reply

Here is a problem on mechanics.

Problem; Two particles move in a uniform gravitational field with an acceleration g. AT the initial moment the particles were located at one point and moved with velocities v1=3.0 m/s and v2=4.0 m/s horizontally in opposite directions. Find the distance between the particles at the moment when their velocity vectors become mutually perpendicular.

Here is my ans. (Got to fig. it out in a concise way after scribbling through pages unsuccessfully. )

The basics of Physics — is Gravity amenable to Quantization? 1

The basics of Physics — is Gravity amenable to Quantization?

This is a very detailed and long article, but written in a very simple language, as it seems to me, describing such concepts as; the basis of expectations of “Quantization of Gravity with other forces” which is colloquially known as Einstein’s dream of GUT — or, Grand Unified Theory, and whether such is possible or not and what we may be missing.

This article also describes briefly Pseudo Forces — check a detailed description here. (web-link)

In detail the basis of Physics Formalism — check a discourse here (web-link) and

What are waves and particle — (a link to an extensive discussion will be provided, upon further review), the discussion is in terms of a Formal POV of Physics — ‘slightly”, but much can be based and expanded on such.

This would be one of the most well written article by me as I would think.

So lets get back to the discussion of our original topic of interest.

The basics of Physics — is Gravity amenable to Quantization?

I like to speak first; about a development of Physics, in this article, that follows a chronological path, rather than, how we look at the cumulative understanding, in modern times, upon which we base our statements and help ourselves be inconsistent, because we forget or rather are oblivious; to the deeper framework, in which things were developed.

— Today I want to focus on Gravity. But before I talk about Gravity; I would like to speak something, on Physics itself. More…

Why is energy conserved? 5

Then we can define Attraction A = int[Zda], this accomodates the changing accelerations. Z = dA/da. Attraction is the total force if you consider x,t,v and a not just x,t. Then you can apply least attraction. A least attraction is what we are seeking in nature. We want to take that path for which attraction is the least and stationary over all available paths. More…

3 aspects of Relativity of Einstein that are actually Newtonian 1

That is how it is defined, the potential of gravity. Kinetic energy is like an individual account in a Bank where as potential energy is like a joint account. Mr. A and Mr. B have kinetic energy accounts in Wachovia. They can have any balance [again speed-of-light constrains this]. But Mr. A and Mr. B have a joint account for potential energy. Potential energy is like a share. You can’t buy your own shares. You can buy in others. But how is it decided? Its decided through your potential. Your potential is defined to be a specific value which is unique for you at a given position. Potential energy is the contribution to the joint account. For a joint account one adds the potential energy contributions from both parteners. Hence if you are farther away from a source of gravity you will have to contribute more energy than if you are near to have a joint account with the source of gravity. In the vicinity of a source of any gravity the potential and potential energy start as –ve and gradually become zero. You’re free only if you are sufficiently away. Therefore less energy is available to the clocks in gravitational field when closer than far away. Clocks will run slower in gravitational fields of closer positions than farther away. More…
