Question
An inflated balloon’s mouth is tied with a thread. The thread is let loose. Newtons third law applies on it. Is the statement true or false?
- True
- False
Hint:
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. His third law states that for every action (force) in nature there is an equal and opposite reaction.
The correct answer is 'True'.
The statement given here is correct.
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. His third law states that for every action (force) in nature there is an equal and opposite reaction.
If a balloon filled with compressed air and its mouth untied(because thread is loose )is released with its mouth in the downward direction, the balloon moves in the upward direction because the air present in the balloon rushes out in the downward direction.The equal and opposite reaction of downward going air pushes the balloon upwards.

A person stops a ball. Newtons third law applies in stopping it. Is the statement true or false?
- A fast moving ball has a tendency to keep moving due to inertia.
- According to Newton's second law, the force with which ball is moving is equal to its mass multiplied by its acceleration.
- When we catch a ball, momentum of the ball is transferred from ball to hand.
