Question

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

Answer 1

Hint: Here we have to apply Newton's first law of motion to get the answer.
There are three laws of Newton.

Complete step by step answer:
Newton’s first law gives us the description of inertia.
Inertia of rest-
The tendency of a body very still to stay very still or of a body moving to keep on going at a consistent movement along a straight line until a force is applied to it is known as inertia of rest.
Inertia of motion-
The essential property of a body because of which it can't change its condition of movement is called inertia of motion.
Motion and rest both can be taken as relative. It implies that if we adjust the fixed reference points for an object, it may be from one point of motion and from the other at rest. For instance, if two people are travelling in a vehicle, then both of them are at rest since the fixed reference point is inside the vehicle.
Relative motion is the measurement of an object’s motion with respect to any other object that is moving or stationary. Thus, in reference to the other moving object, the acceleration is not measured with reference to the earth, but is the momentum of the object as if it were in a static state.
Here the trees and leaves are at rest first. So, the leaves have a tendency to remain in the state of rest.
Thus, when we shake a tree too much, a portion of the leaves may get separated from the tree.

Note:Almost all motion is relative because the objects which are in rest are also in motion and vice versa.
The earth is revolving and rotating which is a motion and we are rotating and revolving along with it.
