An object of mass m at rest is acted upon by a force. When the velocity-time graph of the object is plotted (with velocity on y-axis and time on the x-axis), we get a straight line passing through the origin and inclined to the x-axis. If the force (on the y-axis) versus time (on x-axis) graph is plotted, the graph is a straight line:
1
Passing through origin and inclined to x-axis
2
Passing through origin and coinciding with x-axis
3
Parallel to x-axis
4
Parallel to y-axis
