Special Relativity Flashcards
1
Q
What is Einstein’s 1st postulate?
A
Laws of motion are the same in all inertial frames of reference and all frames are correct.
2
Q
What is Einstein’s 2nd postulate?
A
The speed of light is the same value, where c is the limit
3
Q
What is difference between time dilation and length contraction?
A
t = Outside the event
t0 = In the event
l = Contacted length
l0 = Outside the event
4
Q
What do observers agree on in synchronicity and simultaneously?
A
- Relative speed of motion
- The speed of light
- Simultaneity of 2 events that take place in the same location at the same time
5
Q
What do observers disagree on in synchronicity and simultaneously?
A
- Time between events
- Distance between 2 points in one frame
- Velocity of moving particle
- Simultaneity of 2 events
