Although their linear momenta are equal, their potential, kinetic, and heat energies
are different.
The gun has more heat.
Regarding potential energy, it can vary. But if the shot is anywhere near horizontal
and the shooter doesn't drop the gun, then the recoiling gun has more gravitational
potential energy at any time after the shot.
The fired bullet has more kinetic energy.
Newton said "For every action, there is an equal and opposite reaction." The action is pushing the bullet in one direction. Reaction is the gun being pushed in the other. The energy is speed times mass. The gun masses much more than the bullet, and so will move proportionately slower than the bullet. Which is a very good thing- or the recoil of the gun would kill the shooter.
The mass of a bullet is nowhere near the mass of a gun. A bullet weighs at most a few hundred grains. Most guns weigh at least a couple of pounds, some weigh several pounds (talking about handguns and rifles).
When a gun is fired, the bullet experiences a greater force than the gun. This is due to Newton's third law of motion, where for every action force there is an equal and opposite reaction force. The force from the expanding gases propels the bullet forward with more force than the recoiling gun experiences.
The bullet has a great deal of kinetic energy, because of its high speed. It also has a little bit of potential energy relative to the ground, because of its height above the ground.
When a bullet is fired from a gun, the energy stored in the gunpowder is converted into kinetic energy that propels the bullet forward. The bullet carries this kinetic energy as it travels through the air until it hits a target or loses its energy through friction and air resistance.
The gun weighs MUCH more than the bullet.
Which gun?
Kinetic, potential, and heat.
If the gun is stationary before the shot, then the momentum of the gun and the momentum of the bullet are equal and opposite after the shot.
Newton said "For every action, there is an equal and opposite reaction." The action is pushing the bullet in one direction. Reaction is the gun being pushed in the other. The energy is speed times mass. The gun masses much more than the bullet, and so will move proportionately slower than the bullet. Which is a very good thing- or the recoil of the gun would kill the shooter.
Yes, shooting a gun involves the conversion of mechanical energy into kinetic energy when the trigger is pulled, causing the firing pin to strike the primer in the bullet cartridge, igniting the propellant, which then propels the bullet out of the barrel.
They are exactly equal. The bullet travels faster, and weighs less. The gun recoils more slowly, but weighs much more.
