Velocity quantity, momentum, is a vector and defined by In special relativity, the dimensionless Lorentz factor appears frequently, and is given by where γ is the Lorentz factor and "c" is the speed of light. Escape velocity is the minimum speed a ballistic object needs to escape from a massive body such as Earth. It represents the kinetic energy that, when added to the object's gravitational potential energy, (which is always negative) is equal to zero. The general formula for the escape velocity of an object at a distance "r" from the center of a planet with mass "M" is where
Our Velocity Our Velocity "Our Velocity" is the first single from "Our Earthly Pleasures", the second album from the band, Maxïmo Park. The single was released two weeks prior to the release of the album, on 19 March 2007. The music was written by Duncan Lloyd and the lyrics by Paul Smith of the band.
