Tug of War One team pulls on their end with 1000 N and the other team pulls on their end with 1000 N. What is the tension in the rope? 2000 N? 1000 N? 0 N? 0? Would you replace the rope? 2000 N? No

It is the team that pushes hardest on the ground Tug of War In a tug of war is it the team that pulls the hardest on the rope? Yes? No? It is the team that pushes hardest on the ground

To win, you can: - maintain your stance until your opponent tires and lessens his push against the ground - push harder against the ground than your opponent maintaining rope tension - push harder against the ground than your opponent and increase rope tension.

Question In a tug-of-war, if the action force is you pulling on the rope, - is the reaction force the ground pushing back on you, or your opponent pulling back on the rope, or is it the rope pulling back on you? Fu on rope Fg on u Fopp on rope Frope on u

That’s all folks!
