If velocity is plotted on y axis and time on x axis, the curve obtained is called the v-t graph.
a) If the graph obtained is a line parallel to time axis then the velocity is constant or acceleration is zero.
b) If the graph obtained is an oblique straight line of positive slope, the motion is uniformly accelerated and if of negative slope, the motion is uniformly decelerated.
c) if the graph obtained is a curve of the type 'Of' whose slope increases with time, the acceleration goes on increasing.On the other hand if the graph obtained is a curve of the type 'Og' whose slope decreases with time the acceleration goes on decreasing.
