accerleration gun on
the bullet ? why.
Answers
Answer:
=> As the bullet is propelled through the barrel, it gains momentum. In order for the entire system of the gun and the ammunition to have equal momentum, the gun must gain momentum in the opposite direction from the bullet. Momentum is a vector quantity, having both a direction and a direction.
=> The faster an object is moving or the more mass it has, the more momentum it has in the direction of its motion
=> It can only be transferred between objects. Momentum is conserved because of Newton's third law of motion.
=> The acceleration of the bullet while moving along the gun barrel would be much greater than the acceleration of the gun (acceleration= force mass).
Detailed Explanation:
If the bullet has mass mb and speed vb out of the gun, it has momentum pb given simply by pb = mbvb
in the forward direction. To balance this momentum, the gun recoils with momentum in the opposite direction: pg = -pb, or mgvg = -mbvb.
=> Conservation of momentum is the law that is held true when the gun is fired and a "kick" is felt. When a bullet is fired from a gun, total momentum before is zero since nothing is moving.
=> After firing the bullet there is a momentum in the forward direction.
=> The gun must therefore have the same magnitude of momentum but in the opposite direction so that they cancel each other out leaving the total momentum still equal to zero.
=> For this reason the gun must have a recoil velocity after the bullet is fired.
