Quote ="tvoc" but thinking about it again this morning I can also see the ball travelling forwards from the point of Briers touch before the momentum of the ball in the direction it was travelling from the kick overrides that force.'"
Unfortunately ‘A body continues in a state of rest or uniform motion in a straight line unless acted on by an external force’
If the ball had been moving forward after hitting Briers it would not be able to change direction again unless it hit something else. A previous ‘momentum’ that it might have had is irrelevant.
That Sir Isaac Newton knew a thing or two about Rugby League.
