I have a few questions regarding your explanations, Erland. How can you bring 2 time dimensions independent of each other? What does it mean? I mean time is only 1 dimension.. So youre saying that virtual displacement is the displacement in s-time, which is different from the normal t- time...

I have been reading Classical Mechanics by goldstein for over 2 months. I have encountered the concept of Virtual Disolacement in that book. Some of my friends have told me that it means a very small desplacement that you cannot see.. However, I am not sure if it is right. Then what is the...

Yes, I think you are right. Thanks for clearing my mind. A planet moving around the sun is not be constrained to move in a circle or ellipse. Is that right?

Mr. Studiot, Isnt a chalk falling freely under gravity constrained by it to fall in only one direction? Falling through a wire vertically still one direction, but the constraint is still not imposed by wire but by gravity. Gupta's notes say."The no. of degrees of fr is n=3N-K, where N=no of...

CAn you tell me how it can be 6 degrees? There are 3 degrees of rotational freedom and one degree of chalk going up or down. So that would be 4, right? Please correct my ignorance if I am wrong..
