Document Summary

Unit r study guide: event = physical occurrence that happens at a definite place in space and time, laws of physics are the same in all inertial reference frames. Momentum and ke are conserved in each frame: galilean transformations are incorrect since time is relative not absolute, galilean transformations t = x - t, y = z. Vx = vz, vz = ax, ay = ay. R2: coordinate time: if 2 clocks are synchronized, dclock = c (tb ta, sr units. Light-second = distance light travels in 1 sec. 1 ft = 1 ns, 1 mi = 1 s, travel around earth in 134 ms, distance of moon to earth is 1. 3s, sun to earth in 8. 3 min, to proxima centauri in 4. 24 years, about. 100,000 years across milky way: plotting world-lines on space-time diagram.
