Question Question 3
Explain why some of the leaves may get detached from a tree if we vigorously shake its branch.
When the tree is at rest, the leaves are also at rest. Now when the tree is vigorously shaken, the tree is in motion while the leaves are still at rest, due to inertia of rest. The force acts on the leaves in changing directions. Therefore, the leaves that are weakly attached to the branch fall off whereas the leaves that are firmly attached to the branch remain attached.
