when a tree is shaken vigorously, its fruits and leaves fall down. This is due to the fact that when the tree is shaken, it moves to and fro slightly but its fruits and leaves tend to remain at the rest due to the inertia and hence detach from the tree and fall down...
Fruits fall down when the branch is shaken because when force is applied to shake the branch,the branch comes in motion but the fruits tend to be at rest
due to inertia of rest which results the falling of fruits.
