Prepare and present an experiment to illustrate inertia of rest.

INERTIA OF REST – It is the inherent property of the body at rest to remain at rest until and unless an external force is applied to it and vice versa for other types of inertias.

Mass is a measure of body’s inertia , higher the mass higher the inertia and vice versa.

With a quick pull, a table cloth can be removed from a dining table without disturbing dishes on it due to the Inertia of rest. The inertia of rest of the dishes keeps them where they are.

We can do this experiment at home also, by putting a table cloth or handkerchief on the table and putting one at a time object of different masses , we will start by lighter objects and will do this experiment till we reach some heavy objects.

But keep this one thing in mind that there should be quick pull not a slow pull that is there should be an impulsive action of pull within an instant , and do not choose very long cloths.

After doing this experiment you will observe and learn

many things like :–

1. Inertia of rest in objects.

2. Inertia depends upon mass of the objects.

3. Newton’s first law application.

So kindly do this experiment at home.

More examples on inertia of rest are :-

When we pick a book suddenly(not slowly) the books above does’nt get disturbed.

When we snatch the cloth from the table suddenly the bottle does’nt fall.

Same in the case of dishes.

When we strike quickly with great force on a card on which a coin is placed then the coin falls vertically straight.
