en.wikipedia.org/wiki/Deceleration_parameter

The deceleration parameter q {\displaystyle q} q in cosmology is a dimensionless measure of the cosmic acceleration of the expansion of space in a Friedmann– Lemaître–Robertson–Walker universe. It is defined by: q = d e f − a ¨ a a ˙ 2 {\ displaystyle q\ {\stackrel {\mathrm {def} }{=}}\ -{\frac {{\ddot {a}}a}{{\dot {a}}^{2}}}} q\  ...

Deceleration is the opposite of acceleration. It is the rate at which an object slows down. Deceleration is the final velocity minus the initial velocity, with a negative sign in the result because the velocity is dropping. The formula for acceleration can be used, recognizing that the final result must have a negative sign.

It is the decrease in speed as the body moves away from initial position. It is expressed as. Deceleration can also be called as the negative acceleration. Hence it is denoted by - a. If initial velocity, final velocity and time taken are given, Deceleration Formula is given by. If initial velocity, final velocity and distance traveled are ...

In physics deceleration does not really exist as a stand alone idea, in terms of the English language deceleration has meaning but in physics there is really no such thing as a formula for deceleration. Allong a particular direction acceleration may cause an object to slow down and in English we would call ...

Apr 24, 2017 ... For example, an airplane screeching to a halt must have a high deceleration rate in order to stay on the runway, and an automobile must sometimes decelerate at a precise rate to stay in the flow of traffic. Two equations are useful for calculating deceleration. One involves the time it takes to slow the object ...
