The gun weighs MUCH more than the bullet.
The bullet fired from a gun has greater horizontal acceleration. For vertical acceleration, they are both the same.
When a bullet is fired out of a gun, the bullet's acceleration and the gun's acceleration are equal in magnitude by opposite in direction. This is the cause of kickback from the gun. The reason why the gun doesn't rip your arm off though is because it's sheer size or mass, resulting in a much smaller impact on the object it collides with.
No- or minimal at best. Acceleration of the bullet comes from gas expanding inside the barrel, pushing the bullet. Once it leaves the barrel, (or within a VERY short distance) gas is no longer pushing, and acceleration stops, and bullet begins to slow from air resistance.
Bullets fired from a gun don't accelerate, the decelerate from the moment they leave the barrel.
Depends on the gun. A .22 will have very different pressures from a 30-06.
When a bullet is fired from a gun, it creates a sudden release of gases that exert a force on the gun's barrel and action system. This force, known as recoil, causes the gun to jerk backward in the opposite direction of the bullet's motion. The jerk is a result of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
A bullet fired from a gun
Affix the gun to a target. Load the bullet into a cartridge. Load the cartridge into a second gun. Aim carefully, squeeze the trigger. If you have done everything right, you will have shot the gun with a bullet.
It's the recoil from the force of the bullet being fired. The gun powder pushes the bullet forward and also equally pushes the gun back into your hand.
Chastain - Bullet From A Gun
A bullet does not accelerate after it leaves the barrel of a gun. It will decelerate. You could say it accelerates, but the acceleration would be negative. The bullet is accelerated by expanding gas as it moves down the barrel, and after it leaves the muzzle, there is no more acceleration imparted from expanding gas. We also find that air friction (drag) is acting to slow it down. Think this one through and it becomes obvious.
A bullet leaves a gun barrel because it is forced out by the pressure of burning gasses.
