Packet 10: Tossup 3

Two values of this quantity times a Christoffel symbol plus another quantity equals zero in the geodesic equation. (15[1])Replacing this quantity with rapidity linearizes (15[2])Einstein’s nonlinear formula (15[1])for adding it. The reciprocal (15[2])of (15[1])the slope (15[1])of (15[1])a worldline (15[1])equals this quantity. (-5[3])This quantity is squared in the numerator of (*) relativistic (10[2])beta, (10[1])which appears (-5[1])in the Lorentz factor. (10[3]-5[2])Non-gravitational (-5[1])time dilation occurs when this quantity is different for two observers. (-5[3])In (-5[1])relativity, forces increase (-5[1])mass because this (-5[1])quantity cannot exceed (-5[1])a universal (10[2])limit (10[1]-5[2])denoted c. (0[1]-5[1])For 10 points, (0[2]-5[1])what quantity (10[1])has units of meters per (10[1])second? ■END■ (10[7]0[7])
