I think it will be fundamentally wrong if we come out with an expression having some exponent with dimensions. x multiplied by x equals x ^2. Here u can see 2 is not a physical quantity but a number and therefore dimensionless. In the same manner any expression at the seat of expression has to...

:approve: It is true that I have learnt. I was (and still I am) awestruck by the thought that every form of energy is ... ultimately ... mechanical energy. I am also thinking at nuclear level... (regarding mass energy...) Great exercise I-C

Really wonderful! it seems every form of energy falls in this category... Now I am guessing (unconvinced myself) Mass Energy?

Mechanical word might have coined in mechanics but if I have to chose between mechanical & mechanical and non-mechanical then I will go with mechanical.

Non conservative forces (dissipative) like friction, viscous etc. Work done against conservative forces is stored in one way or other. Work done against electrostatic force is stored as electrostatic potential energy, Work done (at constant velocity) against gravitational force is stored as...

Please consider this argument: According to the charge density equation, charge is continuously distributed. The result you will get in terms of r which is a variable. In final result you can put any value of r (from o to infinity) you get the result. As far as if we are talking about only...

Here C may or may not be dimensionless. Only point to be noted is exponent has to be dimensionless.

Gauss' law involves charge enclosed by the Gaussian Surface and flux linked with that surface. of course the field involved in flux calculation is net. But in any case due to symmetry field will be same at same radial distances and symmetry tell us that filed will be radial. These aspects will...

The standard kinematic equations always give displacement. When initial velocity is opposite to acceleration, particle will stop some time in future and then reverse its direction. If the time considered is less than time of stopping then distance will be same as the disp, but when time involved...

! Here I restrict my discussion to classical physics domain. Potential Energy is defined for conservative forces or field. These conservative forces may be gravitational force, spring force ( obeying Hooke's Law), electrostatic forces (I believe all type of bonds explained in chemical reactions...

Any expression at the seat of power is always dimensionless. e.g. x multiplied by x is x^2. Here 2 is a dimensionless constant. In your question if b = 2 then k = a^2. Which implies that units of k are unit of mass square (e.g. kg square). If were three units of k would be mass cube. One thing...
