Question

Give a simple experiment to illustrate the inertia of rest

Answer 1

Inertia of rest is the inherent property of an object which resist the change in its state of rest.

Aim:  To illustrate the inertia of rest.

Apparatus required :
Transparent Glass tumbler, Coin and smooth card board.

Procedure :
1. Place the card board on the top of the glass and place a coin as shown in the figure.2.Apply a gentle force using fingers to flick the cardboard.

Observation:
we observe that coin drops straight into the glass.
Reason:
According to First law of motion " Every object continues to be in state of rest or in state of uniform motion unless it is compelled to change its state by an external force"
So here , Force was applied to cardboard , where as coin was in state of rest, it continues to be in state of rest due to inertia. Hence it falls into the glass tumbler.
