The velocity of an object that is moving is always the same, it is not necessary. It may also be that its velocity remains different at different times. If the velocity of the object increases or decreases with time, such a condition is called accelerated speed and we use a new amount of 'acceleration' to tell how the velocity changes. If the velocity increases then the acceleration is considered positive, and if the velocity decreases then the velocity is considered negative. If there is an equal change in velocity of an object in equal interval of time, then this acceleration is called 'uniform acceleration'. If the velocity of the object decreases with time, the acceleration is negative, which is called Mandana. Thus the rate of dilution velocity decreases. Take this trivia quiz about Acceleration.
