Does this sound right? You are standing on a log and a friend is trying to knock you off. He throws the ball at you. You can catch it, or you can let it bounce off of you. Which is more likely to topple you, catching the ball or letting it bounce off? Briefly explain what physics you used to reach your conclusion. ----> I think catching the ball will be more likely to topple you because there is less momentum when the ball bounces off you than if you catch it, becasue the rest of the ball's velocity will "go onto you" thus making you topple over, generally speaking.
