1.If you were in spaceship traveling at the speed close to the speed of light (with respect to the earth) you would notice that___________
your pulse rate is different than normal
your mass is different than normal
some of your physical dimensions were smaller than the normal
none of these effects occur
2. Which of the following is not a consequence of Einstein’s relativity?
Simultaneity
Time Dilation
Length Contraction
Mass decrese
3. An object of rest mass of 1kg moving at 99.5% of the speed of light. What is its measured mass?
10 kg
1.5 kg
0.1 kg
0.15 kg
4. A spaceship approaching an asteroid at a speed of 0.6 c launches a scout rocket with the speed of 0.4c. At what speed is the scout rocket approaching the asteroid?
0.76 c
0.96 c
1.00 c
0.81 c
5. Will observers A and B agree on measurements of time if A moves at half the speed of light relative to B?
Observers A and B will agree on the measurement of time and see each other’s time as passing normally.
Observers A and B will not agree on measurement of time.
Observer B will observe the slowing of time in his frame of reference.
No enough data for comparison.
6. In relativistic point of view, what happen to mass as velocity increases?
mass increases
mass decreases
mass does not change
mass decrease first and then increase

Isaac Newton
Albert Einstein
James Clerk Maxwell
Michelson and Morley

21 years
19 years
20 years
20.5 years
9. Which of the following is not a prediction of general theory of relativity?
Passage of time
action-reaction forces
Geometry of space
Propagation of light
What does it implies when the relativistic speed approaches the speed of light?
Newton’s definition of momentum is valid
the momentum approaches infinity.
the momentum decreases dramatically.
the momentum is became equal to the mass of the object.
