Expert Answer
I - slope of graph-I = velocity / time = acceleration
II - slope of graph II = Force / Spring extension = Spring constant
III - slope of graph-III = Force / Mass = acceleration
IV - slope of graph-IV = acceleartion / velocity = reciporocal of time
hence slope of grpah-I and graph-III gives same physical quantity , i.e., acceleration
Area under the graph :-
for graph-I, Area = = distance travelled
for graph-II, Area = = Workdone or stored potential energy in the spring
for graph-III, Area = . No specific physical quantity
for graph-IV, Area = acceleration × change in velocity = power / unit mass
There is no common physical quantity among the area under the curve of all the graphs
