Calculate the interval ∆s2 between two events with coordinates ( x1 = 50 m, y1 = 0, z1 = 0,t1 = 1 µs) and (x2 = 120 m, y2 = 0, z2 = 0, t2 = 1.2 µs) in an inertial frame S.
b) Now transform the coordinates of the events into the S'frame, which is travelling at 0.6calong the x-axis in a positive direction with respect to the frame S. Hence verify that thespacetime interval is invariant.
Calculate the interval Δs2 between two events with coordinates (x1 = 55m, y1 = 0m, z1 = 0m, t1 = 1 μs) and (x2 = 125m, y2 = 0m, z2 = 0m, t2 = 1.6 μs) in an inertial frame S. Now transform the coordinates of the events into the S' frame which is travelling at 0.75c along the positive x-axis with respect to frame S, thereby verifying that spacetime interval is invariant.
Consider two inertial reference frames S and S' in standard orientation so that S' moves along the positive x-axis with constant velocity u relative to S. A particle moves relative to frame S along the x-axis with instantaneous velocity Vx and instantaneous acceleration ax.
(a) Show that the instantaneous acceleration a's of the particle in frame S' is 2 3/2 и, a' =a 1- 1
(b) The proper acceleration a of a particle at a given point P on its world line is defined to be the acceleration of the particle relative to a co-moving inertial frame at P. By definition, the instantaneous velocity of the particle is zero relative to the co-moving frame. As the velocity of the particle changes along the world line, we can imagine there exist different co-moving inertial frames at different points along the world line of the particle. Now suppose u is the instantaneous velocity of the particle measured by a fixed laboratory inertial frame S. Derive the instantaneous acceleration ax of the particle…
