For every action, there is an equal and opposite reaction. Now the bullet is light (low mass) so when a certain amount of force pushes the bullet forward and the gun backward at the same time, the bullet moves fast. The gun is heavy (great mass) so it is slower to accellerate rearward. It will never reach even a small fraction of the velocity of the bullet. But since force = mass times velocity squared, there is an equal amount of energy in the bullet and the butt stock of the rifle.

When the rifle fires, it propels the bullet forward with force based on Newton's Third Law of Motion: for every action, there is an equal and opposite reaction. The force pushing the bullet forward causes an equal force in the opposite direction, which results in the rifle recoiling backward.

What is recoil of a gun?

Sir Isaac Newton's 3rd Law of Motion states that for every action, there is an equal and opposite reaction. A firearm propels a bullet towards a target, the mass (~weight) of the bullet and its acceleration create a force in the opposite direction of the bullet's travel. You can play around with the bullet's mass (~weight) and its velocity to get equal recoil: 1- bullet 20grams, accelerates at 100m/s has the same recoil as: 2- bullet 200grams, accelerating at 10m/s (recoil force = 2000 for both)


When a bullet is fired from a riffle?

Not quite a question yet. If you are asking about the physics, when a rifle fires a bullet, the ACTION of the bullet being pushed out of the barrel is equaled by the REACTION- or recoil, of the rifle pushing to the rear.


Why does a gun not recoil just as fast as the speed of the bullet?

because the recoil is when the bullet forces the gun back and so the bullet creates the recoil and so it can't make it go just as fast


What does the metal spring in a firearm do?

The metal spring critically dampens the gun barrel so that it can recoil and the compensate for the reaction of the action done by the bullet.


What is the recoil of a 308?

assuming that you talking about a .308 Winchester or the 7.62 NATO round recoil is factor of pure physics the lighter the weapon the greater the free recoil (kick).the heavier the bullet the greater the kick. the higher the velocity the more kick.there are many factors involved in calculating the recoil of any firearm.what does the gun weigh ?what is the barrel length? what is the bullet weight? is the gun a bolt action or auto-matic ? is it gas or recoil operated ? does it have a recoil reducer of some type? how effective is this recoil reducer? knowing the interior ballistics of a cartridge is only the beginning of calculating the recoil and barrel flip of any firearm. in my observation over many years most .308 guns have recoil effect of between 7-15 foot pounds of free recoil energy.


Does recoil increase with a shorter shotgun barrel?

Weight is what affects recoil. Cut the barrel, reduce the weight, recoil will increase if all else is equal.


What is a port on a gun?

Typically it is a set of holes in the upper side of the barrel near the muzzle. Part of the gasses pushing the bullet are released through those holes as the bullet passes them. Gasses going UP push the barrel DOWN, counteracting the recoil that flips the muzzle up.


Which will give a lesser recoil on a pistol..an ammunition with a heavier bullet or a lighter bullet?

light


What is the term recoil o f the gun?

Bullet forward, gun back - as in when the gun is fired, the bullet goes forward, and the explosion pushes (recoil) the gun backwards.


What is an example of an action reaction forces?

The recoil of a bullet being fired from a gun is a good example, the action force is the gun pushing the bullet away from the gun and the reaction force is the bullet pushing back against the gun (recoil).


Why recoil of heavy gun is not strong as light gun?

Recoil is the equal and opposite of the force driving the bullet. A heavier gun is a greater mass to be moved by that recoil.


What kind of force is the backward kick of a rifle after its been shot?

This will vary depending on the cartridge fired, and the weight of the rifle. With a heavy target rifle in caliber 22 LR, it will be barely noticeable. With a light hunting rifle in 30-06 caliber, it can be enough force to be painful. With VERY powerful cartridges, such as the .577 T-Rex, recoil may be enough to knock you down. Recoil is the REACTION to the ACTION of accelerating a bullet down the barrel. The weight and speed of the bullet generate the recoil (heavier, faster bullets = more recoil) , modified by the weight of the rifle- heavier= less recoil.
