Suppose an astronaut is moving relative to the Earth at a significant fraction of the speed of light. (a) Does he observe the rate of his clocks to have slowed? (b) What change in the rate of Earth-bound clocks does he see? (c) Does his ship seem to him to shorten? (d) What about the distance between stars that lie on lines parallel to his motion? (e) Do he and an Earth-bound observer agree on his velocity relative to the Earth?
To whom does the elapsed time for a process seem to be longer, an observer moving relative to the process or an observer moving with the process? Which observer measures proper time?
How does modern relativity modify the law of conservation of momentum?
What is隄ゝor a proton having a mass energy of 938.3MeV accelerated through an effective potential of 1.0TV (teravolt) at Fermilab outside Chicago?
(a) What is the effective accelerating potential for electrons at the Stanford Linear Accelerator, if 隄�= 1.00 脳105 for them? (b) What is their total energy (nearly the same as kinetic in this case) in GeV?
