Question

State newton's First law of motion b) Give two examples of inertia of rest *

Answer 1

Answer:

Newton's first law states that every object will remain at rest or in uniform motion in a straight line if no unbalanced external force will act on it

two example of inertia of rest are as follow

1 )suppose you shake the branch of tree initially the leaves are at the rest , when you shake the branch , branch comes in motion but leaves remain in rest and thus it experience inertia of rest .

2) when we beat the carpet with stick, carpet comes in motion but the dust particle remain at its state of rest and separated from the carpet . here dust particle on a carpet fall if we beat carpet with stick and is an another example for inertia at rest

hope it will help you pls

please mark this answer brilliant please follow me

Answer 2

According to the Newton's first law of motion , if a body is in state of rest , it will remain in the state of rest and if in the if it is in the state of motion it will remain moving in the same direction with the same speed unless an external force is applied on it.

examples :

1) First example of inertia of rest: Fall of dust particles from a durries or cloth: We all have seen that the dust particles in a durries or cloth fall off when it is beaten with a stick. This is due to the reason that the beating results in motion of durries but the dust particles remain at rest. Thus dust particles fall off. This is one of the examples of inertia of rest.

2)Second example of inertia of rest: Fall of rider backwards: You must have also noticed that the rider of a horse falls backwards, when a horse starts suddenly. This is also due to inertia of rest of upper part of the body of the rider.
