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).
Continue ReadingOne 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.

Full Answer >Acceleration refers to the change in velocity of a moving object within a certain period of time, either to a slower or faster pace, while deceleration exclusively refers to the negative acceleration (or slowing down) of an object. In layman's terms, acceleration usually only refers to positive acceleration.
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.
Full Answer >A classic example of a projectile motion problem is calculation of the ballistic trajectory of a projectile under gravity. This problem illustrates the basic form of projectile motion problems and is illustrated in a number of simulation games that provide an intuitive way to examine the problem and its solution.
