WebDeceleration (i.e. reducing) is the polar opposite of propulsion (i.e. speeding up). a = (v – u)/t, wherein there is the deceleration, v is the end velocity, u is the initial speed, and t is the time spent, is one method of calculating deceleration. The deceleration value can be calculated using the accelerating formula with a minus number. Webdeceleration injury, impact injury to a body within or upon a rapidly moving object caused by the forces exerted when the object is brought to a sudden halt.
