Newton's 1st Law of Motion states that an object in motion will remain in motion unless acted upon by an external force. This law can help an NFL player during a football game by allowing them to maintain their momentum when running with the ball. For example, if a running back is running down the field and is met by a defender, the running back can use Newton's 1st Law of Motion to keep running by pushing off the defender and continuing to move forward. This allows the running back to maintain their momentum and keep running with the ball.
