You think it makes no difference whether that 1kg mass hits you at

Of course it makes a difference, you idiot! But that is due to its 
relative speed, which is NOT a 'property' of the object, intrinsic or 
'extrinsic'.

An intrinsic property of one object is NOT an Extrinsic property of all
others.
Extrinsic properties DO NOT exist.

Well, forget the words used, then if you don't like them. We can still 
measure the distance between the ends of a moving rod at the same time, 
and get a distance that is not the same as the proper length of the rod.

OK... you get the wrong answer when you use light signals and Einstein's

Exactly! But extrinsic properties such as kinetic energy, velocity, length, etc.
vary depending on the frame from which it is observed.

Neither kinetic energy nor velocity are properties of the rod. An 
absolute length is DEFINED by the rod, the same in all frames.

'Extrinsic' properties don't exist.

Let us introduce some neologisms that, for normal people, should not be 
necessary, but which represent concepts that spr crackpots are incapable of 
understanding.

The "proper kinetic energy" of a rod is zero.
The "measured kinetic energy" of a rod is a frame dependent quantity.

The "proper velocity" of a rod is zero.
The "measured velocity" of a rod is a frame dependent quantity.

The "proper length" of a rod is a fixed non-zero quantity.
The "measured length" of a rod is a frame dependent quantity.

The "proper mass" of a rod is a fixed non-zero quantity.
The "measured mass" of a rod is a frame dependent quantity.

... and so on and so forth.

Fin de siècle scientists were going nuts because experimental measurements
seemed inconsistent with fixed proper length, fixed proper mass, etc.

Lorentz invented a "theory of the electron" (the meaning of the word "electron"
used then is VERY different from the current understanding of the term) that 
assumed actual physical changes to a rod's properties as a result of the 
interactions of the rod's electrons with the flowing aether.

His theory fit experimental observation, but at considerable cost of
abandoning fixed proper length, introducing mathematical tricks like "local 
time", etc. (Contrary to Lorentz, Poincaré saw more to local time than a
mathematical trick, but did not quite achieve a full understanding of
Lorentz's equations.)

Einstein introduced a theory that paid special attention to the act of 
measurement. His theory restored fixed proper length, fixed proper mass etc. 
but showed that measurements of these quantities were frame dependent.

Energy is not a property of anything.

Velocity is not a property of anything.

An absolute Length is defined by an object such as a rod.

Mass is an intrinsic and absolute property of matter.

Why do you bother posting such crap?

There were no such measurements....and any such effects are due to 
entirely different factors.

There are no such observations....except in dingleberry posts to each other.

Poincare wrote Einstein's SR. Einstein merely translated it into German.

Einstein never measured anything.

No experiment has shown length to be frame dependent. A rod is unchanged 
no matter who looks at it.

Yes, of course. Remember, I am inventing neologisms for Henry's benefit. My
"measured mass" is equivalent to the term "relativistic mass" which is a 
deprecated term.

I'm not sure this is an accurate statement. Particle physicists tend to 
speak of invariant mass a lot; synonymous with proper mass. If anything, 
"relativistic mass" or frame-dependent mass seems to be less used these 
days.

As "relativistic mass" / frame-dependent mass
is not only frame dependent, but also direction-dependent,
so it neither an intrinsic object property,
neither a frame-dependent constant.
