Momentum–depth relationship in a rectangular channel Momentum–depth relationship in a rectangular channel In classical physics, momentum is the product of mass and velocity and is a vector quantity, but in fluid mechanics it is treated as a longitudinal quantity (i.e. one dimension) evaluated in the direction of flow. Additionally, it is evaluated as momentum per unit time, corresponding to the product of mass flow rate and velocity, and therefore it has units of force. The momentum forces considered in open channel flow are dynamic force – dependent of depth and flow rate – and static force – dependent of depth – both affected by gravity. The
Gregangelo’s Velocity Circus/Arts and Entertainment physics into the themes and titles of his choreographed performances. Herrera became aware of the Big Bang theory in the 1990s; in 1992 scientists witnessed through a telescope what they thought was a universe coming into existence. Obsessed with the Big Bang theory, Herrera wanted a company name that described the force of everything that exists in the universe. Thus, Herrera thought the equation for velocity (velocity equals distance over time) fit the kinetic nature of circus arts, performance arts, and the arts in general. Finding that art comes into existence through movement is very characteristic of the traditional Whirling
