Everything You'll Have Covered

What are the two basic principles of Einstein's Special Theory of Relativity?

~ The two basic principles of Einstein's Special Theory of Relativity are:

1) The laws of physics are the same in all inertial reference systems that stay still or move at constant speed.

2) The speed of light is always the same in all systems that are stable or moving at a constant speed - regardless of the light source or the observer.

In classical physics, how is the resultant speed of an object found?

~ The resultant speed of an object is found by adding its own speed and the speed of the medium it's in.

Explain how Einstein proved that space and time are dependent upon each other.

~ Einstein combined his two principles to reach the conclusion that whether inside or outside of a stable or moving object, the speed of light can be measured as equal. He, therefore, determined that distance and time must be measured differently by observers at different speeds.
