**TRUE or FALSE:** For any trajectory in a "1+1"-dimensional Minkowski diagram, the slope can be **no greater** than 1.
1. True
2. False
Note:
* Correct Answer: B
* Has to be greater than 1
Two events have a timelike separation. In a "1+1"-dimensional spacetime (Minkowski) diagram (x horizontal, ct vertical), the magnitude of the slope of a line connecting the two events is
1. Greater than 1
2. Equal to 1
3. Less than 1
Note:
* Correct Answer: A
Consider the world line of an object drawn on a Minkowski (space-time) diagram. At any point in that space, the slope of that line is:
1. larger than 1
2. less than 1
3. able to take on any value
Note:
* Correct answer: A
Points that lie outside the light cone for a given event are:
1. accessible no matter where they are
2. accessible for given world lines (trajectories)
3. always inaccessible
Note:
* Correct answer: C
