This quantity for a reference frame must be zero for the frame to be inertial.
Classically, this quantity squared times charge squared is proportional to the radiative power of a point charge. This quantity for a reference frame must be zero for the frame to be inertial. Radius times angular frequency squared has units of this quantity, as does linear velocity squared divided by radius, for an object in (*) uniform circular motion. This quantity's angular counterpart, symbolized alpha, multiplies the moment of inertia to give net torque. Analogously, this quantity times mass equals the net force. For 10 points, name this second derivative of position, and the first derivative of velocity, which is measured in meters per second squared.
