Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. ... Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval.

Answer 2

• The rate of Change of velocity is Called Acceleration , Which can be negative or positive i.e Decrease or increase .
• i.e - when we throw a ball upward the Velocity of Increases first but After reacging certain height due to Pull of gravity towards earth it's velocity decreases which is Called negative acceleration .
