I'm doing this homework on relativity and I'm not very good at it. :( I keep getting things wrong or confused in my head. Please help me to understand this! Thank you in advance!
3. Person A is at rest with a light clock. Person B is in a car moving to the left (as seen by Person A with a light clock). Discuss how each person will perceive time. Use algebra to find the time measured by Person A with respect to how he or she perceives time measured by Person B.
5. The theory of relativity sets an upper limit on the speed a particle can have. Does that mean that there are also upper limits on its energy and momentum? Explain.
(3) A person name A is at rest frame of reference and another person B is moving to the left with respect to person A.
Let the time observed by person A is T1.
The time observed by time second person B is T2.
According to person A the time measured by person B can be determined using time dilation.
The time on moving clock is,
For example if person A observed for 1h and the person B is moving with a speed 80% of speed of light. The time measured by A on moving clock is,
5. The upper limit for speed of the particle is c (speed of light). When a particle moving with speed approximately equal to c, then its mass also varied. Thus, the energy and momentum of the particle also varied.
The momentum of the particle is,
The energy of the particle is,
If the particle is moving with speed of light, then mass of the particle becomes infinity. Hence, the mass should not be infinity.
