Newtons 3rd law of motion?
I don't want to tell my son (std V1 - age 11) that a gun when fired recoils by using reasons like say Newtons 3rd law or law of conservation of momentum How would I explain him (They are not, in any case, the reasons for recoil. How can I explain him or I cant ? (he understands forces but not energy)

When a bullet is fired from the gun, a large force is applied to the bullet by the gun, through explosion of the gun powder, for a short time. During this short time, by Newton's third law equal and opposite force gets applied to the gun for the same short time. Force x time is the impulse. Thus, the same impulse gets applied to the bullet and the gun but in opposite direction. The impulse on the gun is what we call recoil of the gun.

The principle used for the motion of a rocket is based on Newton's third law of motion.
When the fuel in the rocket is ignited;it burns as a result of chemical reaction.
The exhaust gases escape with force through a small opening at the tail end of the rocket.
They exert an equal and opposite reaction force on he rocket.
It is this reaction force which makes rocket move in the forward direction.

First:An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Second:Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). Third:For every action there is an equal and opposite re-action.

Simple.....take an example of u slapping him.....he feels the force but so do u......the force felt by u is in accordance with the N 3rd law....
Every action has equal and opposite reaction......
But also tell him that the reaction force only acts different bodies and not on one body....
Eg.....ur hand would feel the reactionary force which would not be felt by his face....and his face would feel the force which is imparted by ur hand.....but the magnitude or (for him) value of both the forces is same....
Pretty simple.....!!

u can tell him a story or correlate newtons law with examples of ramayana like flying of hunumana and
using visuals of chineese kung fu movies of kicking a man and using recoil from man to jump in air.u can make him to play cricket and telling him the reason why htere is vibration in bat and and why boll goes after getting hit

Well, one way i can think of is tell your son is when you shoot a gun, there is gun power inside the bullet which propels it forward. The explosion acts in both directions, pushing the bullet forwards and the shooter backwards.
I hope it helps =)
Whats (std V1)?

This law is exemplified by what happens if we step off a boat onto the bank of a lake: as we move in the direction of the shore, the boat tends to move in the opposite direction (leaving us facedown in the water, if we aren't careful!).
hope this helps

Just tell him that forces are not "one-way streets".
When object A acts on object B via a force, object B acts on object A with exactly the same force.
