    - The nature of v-t curve is as shown in above figure, when acceleration of a particle is constant but it is non-zero. It is linear function of time.

    - The nature of v-t curve, when acceleration of particle is zero from initial condition is a horizontal line of constant velocity parallel to time axis.

    - When acceleration is a linear function of time, velocity is a 2nd degree parabola of time.
