Schwarzschild radius (sometimes referred to as the gravitational radius) is the distance from the center of an object such that, if all the mass of the object were compressed within a sphere of such radius, the escape speed from the surface would equal the speed of light. It, thus, defines a spherical boundary called the event horizon, commonly associated with black holes, beyond which the events cannot affect an outside observer. Theoretically, any amount of matter will become a black...

A barbell is mounted on a nearly frictionless axle through its center. The low-mass rod has a length d= 0.16 m, and each ball has a mass m = 0.1 kg. At this instant, there are two forces of equal magnitude F applied to the system as shown, with the directions indicated, and at this instant the angular velocity is 60 radians/s, counterclockwise, and the angle α = 20 degrees. In the next 0.003 s, the angular momentum relative to...
