What is the nature of displacement-time graph of a particle moving with constant acceleration ?

What is the nature of acceleration-time graph when the body moves with constant acceleration ?

What is the nature of the distance time graph for an object moving uniformly along a straight long road ?

In the figure gives a speed-time graph of a particle in motion along a constant direction. Three equal intervals of time are shwon. In which interval is the average acceleration greatest in magnitude ? In which interval is the average speed greatest ? Choosing the positive direction as the constant direction of motion, give the signs of v and a in the three intervals. What are the acceleration at the points A,B,C and D?

What will be the shape of displacement-time graph when acceeration or retarddation is uniform?

What does the tangent at a point to the displacement-time graph represent?

What will be the nature of x - t graph for a uniform motion?
