Why does the stability of an object decrease when it's height is increased?
e.g. u pile up cans n the more height u increase the more easy is it for them to get unstable and fall down.
Falling due to piling up has more to with difficulty in balancing.Potential energy does increase with height but in piling up example that is not which is responsible.
so what is the factor?
I think it is the centre of gravity.
