Question

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

Answer 1

When branch of a tree is shaken, it sets into motion. The leaves, however, tend to remain in the state of rest.

As a result, the leaves may get detached from the branch.

Answer 2

When a tree is vigorously shaken, the branches of the tree come in motion but the leaves tend to continue in their state of rest due to inertia of rest.

As a result of this, leaves get separated from the branches of the tree and hence fall down.
