There is no such thing as a formula for deceleration; there is only a formula for acceleration. To find the acceleration, subtract the initial velocity from the final velocity and divide that sum by the time taken. If th... More »

Deceleration, or decrease in speed, can be calculated using multiple different formulas, depending on the available parameters. Some deceleration formulas include a = (v - u)/t, and a = (v^2 - u^2) / (2s). More »

In projectile motion, horizontal velocity is the rate at which an object is traveling parallel to the earth. Scientists calculate horizontal velocity using the formula v = d/t, the same formula used to determine the spee... More »

Rate of deceleration is expressed as negative acceleration. The negative sign indicates that deceleration takes place in the opposite direction as acceleration. Both are as expressed in standard units m/s^2. More »
