Question

If I consider thethe Newton's third law of motion, then is it enough for me to train just my legs and make them very strong, stronger than the other Sumo wrestler to defeat him in a fight? I mean being able to push him out of the ring?

Answer 1

But you often see that when we move an object, we seem to not move at all. That's a deceiving look. The third law says F = F', but F depends on mass from the relation F = ma. So even though both objects get the same force, it depends on how big the mass of each object, the bigger the object, the smaller the acceleration it gets, thus the smaller the distance it travels compared to the other object. We do move backward, but the move is so small that we hardly notice.

there will be an opposing force also so if your force is greater than the opposing force you can push him out of the ring otherwise it won’t be possi
