Relativity Test questions with complete solutions
already passed
1. State the relativity principle The basic laws of physics are the same in all inertial
reference
frames
2. State the assumptions 1. The lengths of objects are the same in all reference
of the Galilean- frames.
Newtonian rel- ativity 2. Time passes at the same rate in all reference frames.
3. The mass of an object, as well as all forces, are the
same in all reference frames.
3. State the assumptions
of Einstein's Special The theory of special relativity explains how space and
Relativity time are linked for objects that are moving at a consistent
speed in a straight line. as an object approaches the speed of
light, its mass becomes infinite and it is unable to go any
faster than light travels. This cos- mic speed limit has been
a subject of much discussion in physics, and even in
science fiction, as people think about how to travel
across vast distances.
4. State the
correspondence The Bohr Correspondence Principle states that the
principle predictions of quantum mechanics must match the
predictions of classical physics in the physical situations
that classical physics is intended to de- scribe, and does
describe very accurately.

train car in an No. Since the windowless car in an exceptionally smooth
exceptionally train moving at constant velocity is an inertial reference
frame and all
smooth train moving at con- of the laws of physics are the same in any inertial
reference frame,
