Explanation:
I disagree with my friend because, the primary difference is not in the kind of atoms, rather it is the arrangement of atoms and molecules that distinguishes solids and liquids.
Atoms are closely packed in solid and hence large cohesive forces act between atoms in solids whereas in liquids atoms are at a distance from each other, hence, less cohesive force act between it's atoms. Moreover, due to loose packing in liquids atoms are free to move in space and hence liquids can flow whereas solids cannot.
In the graph of the force vs the time:
Force is the gradient of the momentum versus the time.
If we get the area under the curve in this graph:
it will be calculated as : force * time
which gives the change in momentum or the impulse.
Therefore, the area under the curve <span>represents the impulse of the force in a graph of force versus time</span>
