Question

1.Can a small child play with a fat child onthe see-saw?

Answer 1

Ummm... sure? It will be difficult for the small child though. I don't have a mathematical proof for that if that's what you're looking for.

Answer 2

if we take the value of moment arm same for both children then the ans is NO. but if we change the value of moment arm like we take small distance for fat chaila and long moment arm for small child then the answer is YES.

Answer 3

The mass of the small child is less than the mass of the fat child and so is the weight. Thus the force by the small child is smaller than the weight force by the fat child. If both children sit at equal distances from the pivot then the torques by them are unequal. The seesaw will rotate at the end of the fat child.

Answer 4

Yes, a small child can play with a fat child on a see saw.
In order for a small child to play with a fat child, the fat child will have to sit nearer the axis of rotation. By that I mean is that we will decrease the moment arm of the fat child.
