Explain the term Velocity-time graph.

1.	Explain the term Velocity-time graph.
Answer» It is a graph of time versus velocity. Its slope t any point gives the acceleration at the corresponding instant. Distance covered in time t equals area under the velocity –time graph bounded by the time-axis. (i) For uniform motion, the velocity-time graph is a straight line parallel to the time-axis. (ii) For uniform acceleration, the velocity-time graph is a straight line inclined to the time-axis. (iii) For variable acceleration, the velocity time graph is a curve.

Answer»

It is a graph of time versus velocity. Its slope t any point gives the acceleration at the corresponding instant. Distance covered in time t equals area under the velocity –time graph bounded by the time-axis.

(i) For uniform motion, the velocity-time graph is a straight line parallel to the time-axis.

(ii) For uniform acceleration, the velocity-time graph is a straight line inclined to the time-axis.

(iii) For variable acceleration, the velocity time graph is a curve.
