Time dilation

[blazarwolf]

1) What is the ratio/good way to think about time dilation in respect to acceleration? If im going 50% the speed of light am I Expirencing time at 50%

 

2) Similar to the above statement but in respect to gravitational time dilation?

 

3) Is there some kinda connection between the two (gravitational/acceleration) as to that my acceleration is increasing my mass, therefore increasing gravitational forces??

 

4) for the primary teachers out there, I need a quick refreser on acceleration, velocity, momentum. What is it that is so important to hiszinberg uncertinty? that is the property that describes both trajectory and speed?

1) it is not a constant ration, it is asymptotic to v=c

 

2) again asymptotic but to escape velocity =c this time.

 

3) no, relativistic mass is a bad concept as it makes you think about things the wrong way. you will not notice any mass increase when you are whizzing along at 0.9999c

 

4)heisenberg uncertainty only really applies on the quantum scale. it basically says that if you measure the position exactly then you will have no idea what the particles momentum is and if you measure the momentum exactly then you will have no idea WHERE it is.

Not sure where you're going with this. Gravitational time dilation isn't normally associated with escape velocity.

is it not? oh. oopsie

Well the actual math is [math]T = T_0 \sqrt{1-\frac{v^2}{c^2}}[/math] where [math]T_0[/math] is the time that passes in the relative rest frame, T is the time the moving object experiences, and v is its velocity.

Time slows down as acceleration increases; especially upon approaching the speed of light.

This effect of time dilation on the amount of half the speed of light if cut to that 50% you would probably stay a moderate speed and not get so slow.

I do not propose I know a bunch about this one. Just some interesting sites to check out.

He's probably thinking about the gravitational time dilation equation:

 

[math]T = \frac{t_0} {\sqrt{1- \frac{2Gm}{rc^2}}}[/math]

 

which is what you get when you substitute the equation for escape velocity:

 

[math] \sqrt{\frac{2GM}{r}}[/math]

 

for "v" in the SR time dilation equation,

Damn math smarties! Even verbally retaded Einstien could answer my questions in statements, not math... actually Einstien sucked at math (1/100000 of my suckage)
