Relative

Special relativity is a significant theory developed by Albert Einstein in 1905 that explains the laws of physics while assuming that the speed of light is constant, regardless of the observer or the source of light.

• TRUE

• FALSE

The speed of light in a vacuum, measured in any inertial reference frame, doesn't have the same value of c, no matter how fast the source of light and the observer are moving relative to each other.

• TRUE

• FALSE

• TRUE

• FALSE

Changes of moving perspective can never make other velocities change from a relative speed, more than the speed of light (V < C), to a relative speed equal to or less than light ( V > C)

• TRUE

• FALSE

When the observer moves away from the source, it is ____, and when the observer moves closer to the source, it is ____.

(answer format; answer - answer) ​

The ____ __ _______ are the same in every inertial reference frame.

____ ________ is the actual time difference between two occurrences that changes from observer to observer as measured by either moving relative to the other. This temporal difference is determined by the relative speeds of the observers' reference frames. Because their space and time coordinates are linked, there is a temporal gap between the two occurrences.

 The total mass of a proton weighs 2.45x10^27 kg which is traveling at a light speed of 0.999 with a c of 1x8^8 m/sec. What is the momentum?

A stationary police car emits a frequency of 900 Hz. Calculate the frequency detected by the observer if (a)the observer is driving away from the police car at 30 m/s and if (b) the observer is driving towards the police car at 25 m/s. (the speed of sound air at 18 C is 361 m/s)
