Why does the gun recoils when it is fired?

Answer 1

conservation of momentum.
Before the shell is ignited the gun/shell have 0 momentum.
When the powder in the shell ignites, the bullet moves away from the gun at high velocity. The gun will move in the opposite direction.
What ties it together is that the m*v product for the bullet (its momentum) is the same as the m*v product for the gun -and these are vector quantities which will add up to be zero.

the gun is more massive than the bullet so the velocity of the gun is less. also you will hold onto the gun and brace yourself against the ground and so the effective mass of the "gun" is actually the gun, you and the earth.

Answer 2

for every action there is an equal and opposite reaction.

but these two equal and opposite forces do not cancel each other because they act on two different objects.

when a gun is fired the bullet moves forward and as a reaction the gun recoils back but with less acceleration due to its greater mass but both the forces are equal in magnitude

u might not believe that the earth is pulling the satellite with some force and the satellite also pull the earth with the same magnitude of force but in opposite direction. though the satellite is too small to apply that much great force.

when we walk forward the earth accelerates backward this is another example of action and reaction forces but always remember that the two forces act on two different objects.

Answer 3

because of Newton's third law of Motion.

For every action there is an equal and opposite reaction.

if you were somehow able to lay a gun on a frictionless surface and have it fire, the weapon itself would move backwards while the projectile would leave the mussle of the gun forward. in the opposite direction. but since the gun weighs so much more, it doesn't travel as far nor as fast as the bullet

Answer 4

Previous responders are correct, it is physics. To get an idea of how much recoil a gun will produce, look at tables provided by ammunition and gun manufacturers about foot/pounds of energy at the muzzle.

Answer 5

For every action, there is an equal and opposite reaction. When that bullet and hot gases explode forward out of the barrel, they push back onto the gun. That push back is the recoil.

A recoil of sorts is what makes rockets go. When their gases burst out of their exhaust nozzles, they push back onto the rocket motor, which makes the rockets go where no one has gone before.

Answer 6

Newtonian Physics: Every action demands an equal and opposite reaction. Pull trigger, explosion occurs, projectile moves forward, gun moves backward.

Answer 7

The bullet pushes the gun in the reverse direction when it leaves the barrel.

Answer 8

The expanding hot gas that is pushing the bullet out of the barrel, is also pushing against the rear of the barrel.

Answer 9

For every action, there is an equal and opposite reaction.

Answer 10

for every action there is an equal & opposite reaction. the law of physics.
