The Second Postulate of Special Relativity States That

Multiple Choice

The second postulate of special relativity states that

A) observers cannot detect their uniform motion except relative to other objects.
B) observers cannot distinguish locally between inertial forces due to acceleration and uniform gravitational forces due to the presence of a massive body.
C) the laws of physics are the same for all observers,no matter what their motion,as long as they are not accelerating.
D) the speed of light is constant and will be the same for all observers independent of their motion relative to the light source.
E) the acceleration of an object is proportional to the applied force and inversely proportional to its mass.
