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).
Know MoreOne formula to calculate deceleration is a = (v - u)/t, where a is the deceleration, v is the final velocity, u is initial velocity and t is the time taken. If distance covered is known but time passed is not known, a second formula that can be used is a = (v^2 - u^2) / (2s), where a is the deceleration, v is final velocity, u is initial velocity and s is the distance covered. The deceleration formulas calculate the rate of decrease in overall speed. Deceleration is typically measured in meters per second^2, or other distance per time unit squared units.
Learn more about Motion & MechanicsThe general formula for finding speed is x = d / t, where "x" denotes the speed, "d" indicates the distance traveled and "t" represents the time it takes to cover "d." Speed is a scalar quantity that is entirely defined by its magnitude without referencing its direction.
Full Answer >In physics, the formula to determine linear speed is expressed as v = s/t. This formula tells users an object's average or non-accelerated linear speed, or velocity. It does this by dividing the total linear distance traveled by the time it takes to travel that distance.
Full Answer >The constant speed formula is defined as the ratio of constant distance traveled divided by the amount of time taken to travel the respective distance. In other words, speed = distance/time.
Full Answer >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.
