Question

Suggest a suitable physical situation for each of the following graphs (Fig):

Answer 1

$A$

The graph shows that initially the body was at rest. Then gains constant speed for some time. After that the velocity reduces to a value in negative direction and then after some time it becomes constant. It is similar to the a football being kicked and then it rebounds from the wall and moves in with negative direction.

$B$

The graph shows that the velocity decreases from a positive value to a negative value and at an instant its value decreases suddenly. The motion of a ball falling from a height on a ground and rebounding back is the process that relates to the graph.

$C$

The graph shows that a body is initially moving with an uniform velocity and then suddenly the acceleration increases and decreases for a very small instant and then again it becomes zero. The striking of a hammer on a nail is the same process that explains the graph.
