​

Answer 1

Explanation:

This can be explained with the help of the concept of inertia.

▪️✴️EXTRA INFORMATION ✴️:-

Law Of Inertia :-

An object will continue to be in the state of rest or in a state of motion unless an external force acts on it.

THREE TYPES OF INERTIA ARE :-

Inertia of Rest :-

When the resistance is offered by the body to continue in the state of rest unless an external force acts on it.

Inertia of Direction:-

When the resistance is offered by the body to continue the motion in the same direction unless an external force acts on it.

Inertia of Motion:-

When the resistance is offered by the body to continue to be in the uniform motion unless an external force acts on it.

Examples of Law of Inertia:-

→ Sudden start of the lift

ANSWER :-

Initially the tree and the leaves are at rest by inertia. Hence, by Newtons first law of motion, it continues to be in the state of rest unless acted by an external force.

Hence, when tree is shaken, tree is in motion but the leaves are still at rest. When the force of shaking is greater than the force which binds the leaf to the branch, it falls down.

Answer 2

Answer:

${\boxed{\boxed{\bold\colorbox{cyan}{ Answer}}}}$

Explanation:

Some leaves of a tree get detached when we shake its branches vigorously because branches comes in motion while the leaves tend to remain at rest due to inertia of rest.
