state the explain law of conservation of linear momentum briefly explain recoil of gun during firing of bullet suitable diagram
Answers
According to the law of the conservation of linear momentum, the total momentum before and after the collision, is always remains conserved, if no force acts on the body.
This also means, that the total momentum of the system remains constant.
Whether we are talking about any collision, either elastic, or inelastic, Oblique, or semi elastic -semi inelastic, momentum always remains conserved.
That was the basic definition of momentum conservation.
Proof ⇒ Since, Fnet = 0
Thus, By newton's second law,
Fnet = dp/dt
∴ dp/dt = =
dp = 0
p₂ - p₁ = 0
∴ p₂ = p₁
Thus, Initial momentum = Final momentum.
Now, If you are asking an example of gun fire, then let me tell you.
Initial velocity of the system is zero. Thus Initial momentum is zero.
When the gun moves out, then it moves forward, but to balance the momentum so as to make it overall zero, momentum acts in backward direction, thus, gun moves little backward.
Mathematically,
Mass of bullet × velocity of bullet - Mass of gun × Velocity of gun = 0
Hope it helps.
Answer:
it states that the total momentum of isolated interacting particles are conservd. suppose an isolated sys. consists of n particles.
