Question

The v-t graph of a body at rest is ____.

  1. A straight line parallel to the x-axis 
  2. A straight line perpendicular to the x-axis 
  3. A straight line coinciding the x-axis 
  4. A straight line coinciding the y-axis 

hintHint:

A straight line coinciding the x-axis

The correct answer is: A straight line coinciding the x-axis


    As the velocity of the body which is at rest is zero at all the values of the time, the v-t graph of a body at rest is a straight line coinciding with the time‐axis i.e., x-axis.
