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

Vigorous shaking of tree branches applies mechanical stress, inducing rapid motion. This stress affects leaf attachments, subjecting them to shearing forces and friction against the surrounding air. Weakened connections due to aging or disease make leaves more susceptible to detachment. Inertia resists sudden changes in motion, contributing to the stress on leaf attachments. The collective effect of mechanical stress, dynamic forces, weakened connections, and natural responses of trees to external stimuli results in the detachment of leaves during vigorous shaking, shedding older or damaged leaves as a survival response to environmental stressors.
