Question
1. Albert views Henry moving by at a constant velocity. Henry has a light clock and also a stopwatch which were synchronized when at rest. As Albert views these two moving clocks, which of these statements would be true according to Albert? a. The light clock runs slow compared to the stopwatch. b. The stopwatch runs slow compared to the light clock. c. The two are synchronized but run fast. d. The two are synchronized but run slow.2. In the game of space billiards with Albert at rest, Henry’s space ball changes vertical velocity less than Albert’s. Albert believes in the conservation of momentum, so he believes for momentum to be conserved,
a. The collision must be elastic. b. The mass of Henry’s space ball must be less than his. c. The mass of Henry’s space ball must be equal to his. d. The mass of Henry’s space ball must be greater than his. 1. Albert views Henry moving by at a constant velocity. Henry has a light clock and also a stopwatch which were synchronized when at rest.

Explanation / Answer
1.
If both clocks are moving at the same speed then they remain synchronized. If they are moving with respect to the observer (Albert) then they will run slow.
So the option d is right.
