I have a question. if two interital observers measure each others clocks to be moving more slowly, it seems that the time dilation effect is just a question of measurement...in other words, time only APPEARS to be moving slowly for either one, but its not like they really age more slowly...
I see the point of your queston. It's relative. fine. but what about the case where one twin ends up older than the other. In that case, time objectively moved more slowly for one of the twins. But I guess that's not really an inertal frame.
I think i get the first part though..
In...
Why will they measure the same clock tick at different rates? The difference in measurement is due to time dilation is it not?
Is it true to say that time flows differently for observers moving at different speeds? For example, if some one is going 100 mph and another is going 1000 mph...
I'm confused..I thought time moves differently for objects moving at different velocities. Do a clock appear to run more slowly or does it 'really' run more slowly?
Ok maybe I should state it this way:
The time and distance of objects in motion can be measured differently depending on one’s frame of reference. This means that two people can get different results when measuring the time and distance of moving objects and they both can be right. The...
The laws of motion are not independent of time and place. Time and space are values that can be different depending on one’s frame of reference. Moving clocks run slower than stationary clocks and moving rulers are shorter than stationary rulers. This means that two people can get different...
In order to do this RIGHT you need to use 4 vector analysis which does
indeed have directions to it. The E = p*c is the magnitude of the
momentum. What is right is E = sqrt(p^2*c^2) where p^2 is really the
inner product of the regular momentum (as a vector).
The virial theorem says that <T> = <V>/2, so the kinetic energy is
double the potential for a 1/r potentialv Also,we know that Newton's Third law works for gravity, which is a 1/r potential.
The viral theorm works with the kenetic energy being double the
potential for 1/r potentials only. The general expression of it is KE = PE/(1-n) where n is the power of the r. In fact, with a central potential Newton's third laws works great (gravity?!).
If the force is concervative in nature then that means that the
only thing that matters in regards to the work is the where you started
with regards to the center and how far from the potential you are when you ended. If it isn't, then the work on the system (if there is any) will depend on...
I agree. But Newton third law is a general principle that serves as a guide in solving particular engineering problems. As a guiding intuition regarding the general equilibrium of momentum, it is correct.
In fact it may be formulated this way...
The Third law in effect states the net...
but that doesn't make Newton's second law wrong, force is
still always the change of momentum with respect to time in a system.
If that wasn't true once then that is the exception to Newton's second
law. In other words if we have moon orbiting a planet, then the gradient of
the potential...
My point is that Newton's third law is neither linear nor agular. It is general.
It states that generally momentum is conserved. And generally speaking, that is correct.
The third law is very simply stated:
action=reaction
and if one bears in mind that force is defined is at the...
