Question

Q. 12. (i) State Newton's third law of motion.
(ii) If someone jumps to the shore from a boat, the boat
moves in the opposite direction. Explain.
(iii) When air from an inflated balloon is allowed to be
released, the balloon moves in a direction opposite
to that of air. Explain. R+A (Board Term-I, 2012)​

Answer 1

Answer:

1) every action has an equal and opposite reaction

2)yes it's because the force acting on your leg is backwards to move your body forwards but nothing can move without friction (other wise it slips.as friction between water and boat is less but between u and boat is more as boat acts with u as a system creating an equal and opposite force on water

3)yes air moves from higher pressure to lower pressure as a result inside balloon pressure is more as a result when inflated it will move out wards to balance the entire state an equal force and momentum is done on the balloon to conserve total energy by Newton's 3 Rd law
