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 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 beta, which appears in the Lorentz factor. Non-gravitational time dilation occurs when this quantity is different for two observers. In relativity, forces increase mass because this quantity cannot exceed a universal limit denoted c. For 10 points, what quantity has units of meters per second? ■END■
ANSWER: linear velocity [or v; reject “angular velocity”]
