SUMMARY
Angular momentum is conserved about point A during a collision, as established by the equation integral(M,A dt) = H,2A - H,1A, where M,A represents the moment of all forces about point A. The effect of gravity is negligible during the brief duration of the collision, allowing for the assumption that the angular momentum before the impact (H,1A) equals the angular momentum after the impact (H,2A). This principle holds true despite the presence of a weight causing a moment about point A, which is disregarded due to the short time frame of the collision.
