An object has a uniformly acclerated motion. The object always slows down before the time, when its velcity becomes zero. Establish this statement graphiclly when (i) both initial veocity (u) and acceleration (a) are positive(iii) (u) is positive and (a) is begative and (iv) both (u) and (a) are negativ e.

When both u and a are positive : In such a case , the v - t graph will be as shown in figure. At the time corresponding to point A, the velocity becomes zero. It can be seen that before this time, the velocity is negative but its magnitude decreases with time till it becomes zero at A
