what can you conclude from the following graph about the state of motion of an object
(a) Displacement - time graph is parallel to the time axis.
(b) Velocity - time graph is a straight line making an angle with the time axis.



​

Answer 1

Answer:

a) Complete answer:

Given that the time-displacement graph of a particle is parallel to the time-axis. That means if the distance-time graph of the object is parallel to the time axis then the particle has not covered any displacement with change in time. i.e. the particle is at rest.

b) (ii) Velocity-time graph is a straight line making an angle with the time-axis. The conclusions are: (i) The body is at rest when the displacement-time graph is parallel to the time axis. (ii) The body has uniform acceleration when the velocity-time gaph is slightly inclined with the time axis.
