From the velocity-time graph, we can determine :

1. The displacement of the body in a certain time interval.
2. The acceleration of the body at any instance.
3. Both (a) and (b)
4. None of these

Out of the following, the correct displacement-time graph for uniform motion is:

The velocity-time graph of a body in motion is a straight line inclined to the time axis. The correct statement is —

1. velocity is uniform
2. acceleration is uniform
3. both velocity and acceleration are uniform
4. neither velocity nor acceleration is uniform.

For a uniformly retarded motion, the velocity-time graph is:

1. a curve
2. a straight line parallel to the time axis
3. a straight line perpendicular to the time axis
4. a straight line inclined to the time axis.
