Re: Dimensions of mass

[RC Macaulay]

Starting a large electric motor across the line can be thought provoking if 
you are observant. The motor seems to start, then attempt to rotate in 
reverse for an instant  as it begans its speed climb to rated rpm. The rate 
of acceleration " wobbles".
I have never tried to track the actual rate of acceleration vs time with 
recording instruments, but the vibration monitor can make one wonder if 
mass can be visualized as "elastic".

It is interesting to find that the definition of
acceleration is lopsided. This leads to acceleration
being given dimensions which are biased,
i.e. [L]/[T]^2
You can see this for yourselves by going though the
process of defining acceleration's reciprocal starting
with the inverse of velocity, namely, change in time
per unit length.
The only unbiased way to treat acceleration and its
inverse democratically is to use
[L].[L]/[T].[T] = [L]/[T].[L]/[T] or velocity squared.
What a mess. It's not just Mass that's been ridden over
roughshod. Simone Weil was right.
