What is the only constant measurement for all observers in the universe, regardless of their motion?
The speed of light
What are the postulates of Einstein’s theory of relativity?
The laws of physics are the same for all observers in uniform motion
The speed of light is self-determined, not affected by the motion of an emitter
What effect does length contraction describe?
Moving objects appear to contract along the direction of motion for observers outside the frame of reference
When are Newton’s definitions more useful than Einstein’s?
When speeds are significantly less than the speed of light, making relativitistic changes more than negligible
