Round 10: Tossup 3

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

ANSWER: linear velocity [or v; reject “angular velocity”]
