[and make sure that you place the boundaries around the "system" so that both gun and bullet remain inside]BvU said:You need a constant force to keep the gun from dropping to the floor. But to calculate the kickback you can use conservation of momentum in the direction the bullet flies.
The law of conservation of momentum states that the total momentum of a system remains constant in the absence of external forces. In a non-isolated system, external forces such as friction or air resistance may act and change the total momentum of the system.
In a non-isolated system, the change in momentum of one object is equal and opposite to the change in momentum of another object. This ensures that the total momentum of the system remains constant.
The momentum of an object in a non-isolated system can change if there are external forces acting on it. This change in momentum is equal to the net force acting on the object multiplied by the time interval during which the force acts.
No, the law of conservation of momentum is a fundamental law of physics and cannot be violated. In a non-isolated system, the total momentum may change due to external forces, but the change in momentum of one object will always be equal and opposite to the change in momentum of another object, keeping the total momentum constant.
The law of conservation of momentum is applied in various real-life situations, such as car collisions, ballistics, and rocket propulsion. It helps in understanding and predicting the motion of objects and is an essential principle in the field of mechanics.
