At my house I was playing billiards with my brother. When he struck the white ball is surged into his striped ball and went into the pocket. This is because when he strikes the ball it has more momentum then the striped ball. The two balls may have the same mass but hitting the white ball gives it a high velocity so it has a high momentum. Based on the law: P=MV, the striped ball has no momentum. This is because the ball has a velocity and any number multiplied by 0 has no value. So when the white ball's high momentum hits the striped ball, the momentum splits between the two balls and sends the striped ball towards the pocket while the white ball has very little momentum left.
