👉 A decelerator, also known as a deceleration device or brake system, is a device that slows down an object by applying a force perpendicular to its motion. In simpler terms, it uses friction to slow down objects. Decelerators are used in various applications such as automotive braking systems, spacecraft propulsion, and even some types of aircraft, where the decelerator acts like a brake or other type of braking mechanism. The primary function of decelerators is to provide a temporary reduction
