Question

when you realise an inflated but united baloon why does it fly across the room​

Answer 1

Answer:

Air escapes from the balloon that carries momentum. By momentum conservation, the balloon acquires momentum which is exactly opposite to the momentum of the escaping air. Therefore, it flies in a direction which is opposite to the velocity of the escaping air.

OR

According to Newton's third law of motion "for every action, there is an equal and opposite reaction".

As a blown up but the untied balloon is released, the air trapped inside the balloon pushes out of the open end. This causes the balloon to move forward.

The force of the air escaping is the "action"; the movement of the balloon forward is the "reaction".

Answer 2

Explanation:

Air escapes from the the balloon that carries moment . By conservation,the balloon acquires momentum which exactly opposite to the momentum of the recapping air.
