WebSpecific Impulse. The specific impulse of a rocket, I sp, is the ratio of the thrust to the flow rate of the weight ejected, that is where F is thrust, q is the rate of mass flow, and g o is standard gravity (9.80665 m/s 2).. Specific … Delta-v (more known as "change in velocity"), symbolized as ∆v and pronounced delta-vee, as used in spacecraft flight dynamics, is a measure of the impulse per unit of spacecraft mass that is needed to perform a maneuver such as launching from or landing on a planet or moon, or an in-space orbital maneuver. It is a scalar that has the units of speed. As used in this context, it is not the same as the physical change in velocity of said spacecraft.
