zrychlení, zvýšení rychlosti
the constant speed reached by a falling object when the drag force equals the gravitational force pulling it downward, resulting in no further acceleration
konečná rychlost, mezní rychlost
the study of the design, development, and operation of aircrafts, focusing on principles of aerodynamics, propulsion, and material science
letectví, aviatika
