Delta-v (Δv) is a term used in physics and astrodynamics to describe a change in velocity. It quantifies the amount of effort needed to change an object's velocity and is often associated with space travel and spacecraft maneuvering. Delta-v is crucial for missions that involve changing orbits, escaping gravitational fields, or executing course corrections.
