why some of the leaves may get detached from a tree if we vigorously shake its branch.?

Q: Explain why some of the leaves may get detached from a tree if we vigorously shake its branch.

Sol: When we shake a branch of a tree vigorously, some of the leaves may get detached on account of inertia of rest of the leaves. The branch comes in motion and the leaves try to be in the position of rest. Therefore, they get detached.
