    Revolution under the influence of a central force

    Hello Dale and A.T. Thank you for your reply. I am trying to figure out the equation of motion of Earth in case there is no rotation, and to figure out whether that equation would include a term to show the "rotation" of a point on the periphery of Earth relative to Sun. My ultimate aim is to...

    Revolution under the influence of a central force

    Thanks so much. I actually used the word "pseudo" to signify that the rotation appears with reference to the sun, and there is no real rotation on its axis. My choice of words may be wrong, but I hope I have conveyed the meaning. Anyways, is it possible to have the derivation of an equation in...

    Revolution under the influence of a central force

    My dear friends and fellow Physics enthusiasts At the very beginning, I offer my unconditional apologies for such a delayed response. Unfortunately, I was too tied up to come back here and post a coherent reply to this discussion. What I am looking for is a mathematical way to represent this...

    Revolution under the influence of a central force

    Thank you all for your replies and insights. I have been extremely busy during the last few days, so could not reply in a timely manner, my apologies for that. I would surely go through the points raised here in detail and come back. Though one thing I must disagree, that my title consists of...

    Revolution under the influence of a central force

    Nope, there is no rotation of the pebble about its own axis

    Revolution under the influence of a central force

    Thanks so much, Tom. I totally agree. But why the example of rotating something by a string is not conforming with this idea?

    Revolution under the influence of a central force

    Let's put it in another perspective. If I tie a pebble with a string and rotate it around my finger, will the position of the knot change? Please understand, I am not trying to argue, but I am trying to clear the misunderstanding.

    Revolution under the influence of a central force

    Hello friends and fellow Physics enthusiasts At the beginning let me confess that I am more of a sleeping member though I do follow this forum quite closely. Today, I am posting to seek some help from fellow Physics educators. I hope this is the right section of the forum to post, if not, I...

    Ideas for science fair project

    Have you checked out NASA website? There used to ideas of wonderful science projects (though I did not pay any visit to the site lately due to scarcity of time).

    Calculating Moment of Inertia with Examples for Beginners

    You have used the FORMULA not the THEOREM. reread the theorem. Igive youa hint: In this case the distance of one of the balls from the axis is 0 and the other is 4m. You did not take this into account. Do not go by the formula but go by basic knowladge :).

    Diffraction of light from a single slit and on a wire

    Generally thinner the wire better is the effect- though mathematically it is related directly with thw wave length of incident EMW. The diameter must be small w.r.t the wave length otherwise you will not be able to see the phenomenon. Regards SRC

    What is the cause behind the Coandă effect?

    The Coanda Effect has been discovered in1930 by the Romanian aerodynamicist Henri-Marie Coanda (1885-1972). He has observed that a steam of air (or a other fluid) emerging from a nozzle tends to follow a nearby curved surface, if the curvature of the surface or angle the surface makes with the...

    How do you know that there's an electron in the hydrogen atom?

    Well you may ascertain the presence in two ways - experimentally & mathematically. In my opinion they complement each other. One good example is using spectral anlysis of excited H atom and then analysing the result mathematically. Quantam mathematics can also be used to show this -as in...
