The units of momentum are joules*seconds/meter. I've tried to explain
this to you before. It is dangerous to look at the units of a number
and try to derive physical basis from them. Energy has units
kg*m^2/s^2, but it also has units farads*volts^2, and it is dangerous
to say that one is more fundamental than the other.

and waht are the dimensions of Jaules ? .........(as more basic

common
it is imposible in righ tphysics that a physical entity
like say energy or momentum can eescape to othere basic
dimentions
afaik th eonly basic dimensions are
in mks kilograms meterss and seconds
if you use another system it must be the same basic
dimensions or else something is wrong in your analysis.

you have to go to the scratch!! you cant avoid coming to the same

1 see what Brian wrote to you
he is probably more expert on that subject than both of us
because
he always deals with it.

2 why are Farads and Volts *defined as MKS units*

3 i suggest you will give much more importance to dimension analysis
because that is an important simple but powerful 'watch dog'
to examine quickly 'if you are on the right track'


later i will have another question to you.

The problem is that you're ascribing too much *physical* importance to
a *convention* used to set up a system of units.

Indeed, SI and MKS, for the sake of utility, make some
general 'homogenised' assumtions about Maxwell fields.

In interpreting the validity of an electromagnetic expression,
it is frequently helpful to see it in cgs and some
of the other time and homogenity variations which exist.

This whole thread is a waste of time...

See, the Italians have proven that the speed of light is no longer a
constant...

Now, the speed is different depending on what frame of reference you are
actually measuring it in.
