Question

How do the weights of the tug of war teams affect the match

Answer 1

In Newton's Second Law of Motion, it simply states that mass x acceleration= force. So if there's more weight on one side and the same amount of acceleration on both side, then the side with more weight has more force. And with more force it tugs it more than the other side.

Answer 2

Because when the players lean towards their side, gravity pulls them backwards, it also makes it harder for the other side to pull someone so heavy. It's like a kid trying to pull their parent. Their parent is so much heavier that if the parent doesn't want to move they won't.
