physics, tug of war

1) What if both sides pulled with the same amount of force but one side is heavier than the other?
What if they played in space?
does putting the strongest in the back change anything?

2) What if both sides pulled with the same amount of force but one side is heavier than the other?

3) The heavier side will win because it will take more force for them to be moved by the lighter side.

4) We discovered that friction was the key to winning a tug-of-war match, and that the team with less friction will nearly always lose. we discovered this by doing a tug-of-war match with one team on a tarp with soap. We also did online research to discover that it would be impossible for one side to be pulling harder than the other.

5) Because it's impossible for them to be pulling at different strengths, but because the heavier side has more mass, and therefor more friction and downward force, it's harder to move them and they'll win. This would be Newton's third law.

  6)
 a) Jason Williams
b) I learned that not only is it impossible for one team to pull on a rope harder than another, but also that friction decides the  winner more than strength.
c) I did some of my own research and wrote the blog post
d) I believe that I deserve the same points as the average group, but I would like more.

a)Andrew Nguyen
b)I learned that it takes the same amount of force on both sides to hold it. and it takes to forces(a pair)
c)i wrote out the original plan and notes
d)I think i deserve the same amount of points as the average group.
