Two Stage Rocket
Suppose the motion of the two-stage rocket or the corresponding velocity-time graph below. The rocket has two successive fuel stages followed through a free-fall motion (no fuel). Within the two fuel stages, the rocket experiences an upward acceleration of +10 m/s/s and +4.29 m/s/s correspondingly. This acceleration is depicted through the slope on the velocity-time graph.
Lorentz Transformation: The postulate of STR is proposed by Einstein in 1905. The two postulates are: 1. Principle of equivalence: According to this "The laws of physics
