<p>An electron is limited to travel at speeds less than c.
Does this put an upper limit on the momentm of an electron?
If so what is this upper limit</p>
<p>I noe I need to se equation mv/ sqrt(1-(vsquared/csquared)</p>
<p>but don't get it still :(</p>
<p>use* equation</p>
<p>I don’t think so, because:</p>
<p>lim (as v->c) is mc/sqrt(0) which is undefined.</p>
<p>in other words, v going towards c, but m is getting closer and closer to infinity</p>
<p>ooo so there’s no upper limit?</p>
<p>also can somebody answer this: will two events that occur at the same place & the same time for one observer be simultaneous to a second observer movng with respect to the first?</p>
<p>I think answer is no… but someone in this forum said yes.
can you give a reason for yes/no?</p>
<p>no, momentum just continues to increase as its speed gets closer and closer to c. I don’t know how else to explain it. If you were to graph it, (momentum on y axis, v on x axis) there would be a vertical asymptote at v=c</p>
<p>brahms do you have any idea about this one?
will two events that occur at the same place & the same time for one observer be simultaneous to a second observer movng with respect to the first?</p>
<p>I don’t think so. I know that they don’t occur at the same time, but I don’t know about place.</p>
<p>Is relativity even on the AP exam? I know it’s not on physics C, because I took that one, but is it on physics B?</p>
<p>iono we’re learning “modern physics” after ap exam gahhh</p>
<p>Is this like time dilation and length contraction?
Because anything moving at the speed of light or near it appears to be shorter, and experiences less time relative to a stationary person.</p>
<p>This is not in AP btw. Ya it’s modern physics, it’s in SAT II.</p>
