Mass (say) 1 kilogram. Then we can measure the mass of any other object in the universe by colliding it with the reference object and measuring the accelerations. Additionally, mass relates a body's momentum p to its linear velocity v: and the body's kinetic energy "K" to its velocity: The primary difficulty with Mach's definition of mass is that it fails to take into account the potential energy (or binding energy) needed to bring two masses sufficiently close to one another to perform the measurement of mass. This is most vividly demonstrated by comparing the mass of the proton in the
Velocity (newspaper) in Louisville, and gay life. Regular weekly features included "The Bar Hopper", in which a local tavern was profiled; "The Party Crasher", a photo-story from the weekend's parties; and "What I'm Into", a mini-profile of a local person. "Velocity" was discontinued during a round of budget cuts by Gannett.
