In general physics, delta-v is a change in velocity. The Greek uppercase letter Δ (delta) is the standard mathematical symbol to represent change in some quantity. Depending on the situation, delta-v can be either a spatial vector (Δv) or scalar (Δv). In either case it is equal to the acceleration (vector or scalar) integrated over time: * Vector version: * Scalar version: If acceleration is constant, the change in velocity can thus be expressed as:where: * v0 or v0 is initial velocity (at time t0), * v1 or v1 is subsequent velocity (at time t1). * v * t * e
