Question

(a) Some of the leaves get detached from a tree if we vigorously shake its branch.​

Answer 1

Answer:

due to the inertia of rest

Explanation:

When the tree is at rest, its leaves are also at rest. But when we bring the tree in motion by means of shaking it, due to the inertia of leaves they still tend to be in rest. Thus force is acting on leaves vigorously with changing direction rapidly. This results in detaching of leaves from the tree

Answer 2

Answer:

Due to its property called inertia.

Explanation:

Inertia is the resistance of any physical object to any change in its velocity.
