Relativistic Momentum | Physics with Professor Matt Anderson | M29-06

[@khadimhussainmuzafari7061]

Hello professor Matt Anderson. How are you? I have a question for you. How the muons have difference speed and difference life time? Please explain sample to me. Thanks.

[@pleb1235]

I like your video. Very nice.

[@yoprofmatt]

Thanks. Cheers, Dr. A

Dr, since the mass and lambda both are same in these two cases, why couldn't we use 2P1 = P2 2*lmbda*m*u = lambda*m*v 2*0.37c = v v = 0.74 c

[@juniorcyans2988]

Nope! Because gamma ( not lambda) contains v.

[@alazrabed]

Indeed you cannot, as commenter above pointed out. In fact, you can verify that by changing the value of the question, you could easily get v2 greater than c. That is precisely the defect of classical mechanics we're trying to avoid in this lecture. To go a little further, having a gamma that is a function of speed allows you to increase the energy boundlessly without overcoming c (or equivalently accelerates indefinitely).

Fantastic 😎

sorry I drifted off...WTF...I'll have to go back.

The gold medal? Wow, I'm honored. Cheers, Dr. A

[@Al-cynic]

Could you not have said 'I Am Batman' after that long pause, You have a definite Michael Keaton vibe going on (and I think he is as good as oldman and malchovich), but obviously pissed off the wrong people!
