one suresh father fired with his gun in the air. Firstly he hold the gun tightly with his shoulder. What is the phenomena behind this. Is it first law of motion?
Answers
Answer:
No it is not first law of motion
Explanation:
it is third law
there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A.
Third law of motion is behind that person hold the gun tightly with his shoulder while firing
Explanation:
third law of motion : ( law of conservation of momentum)
To every action there is always a reaction equal in magnitude but opposite in direction
mass of Bullet * velocity of bullet = mass of gun & velocity of gun (in opposite direction )
velocity of bullet is Quite high and difference between mass of Bullet and mass of gun is not that high
Hence reverse velocity could be high and can cause injury.
But if person hold the gun tightly with his shoulder
then mass of system become mass of person + mass of gun which is quite high compared to mass of bullet
hence reverse velocity would be negligible
