Question

why leaves of tree may get detached from branch when we shake the branch of tree?

Answer 1

Leaves of tree may detqched from branch when we shake because when we shake branch it comes on motion. Hence leaves remain in rest and detached from tree due to inertia of rest

Answer 2

Answer :-

When the branch of the tree is shaken, the branch moves in a to-and-fro motion. However, the inertia of the leaves in attached to the branch resists the motion of the branch. Therefore, the leaves that are weakly attached to the branch fall off due to inertia whereas the leaves that are firmly attached to the branch remain attached.
