it doubles
When we use the simple formula for potential energy as PE = m g h then what our community says is true. But as we have to use the expression for potential energy as PE = - G M m / r^2
Here r is the distance of the object right from the centre of the earth. But h in the previous expression is the height right from the surface of the earth. So we have to work it out properly.
it means potential (as in my case, Gravitational Potential energy)
It decreases[:
It decreases as the square of the distance.
the gravitational force between them decreases.
It increases.
Yes. For example, this happens in a seesaw.
I assume you mean the gravitational potential energy. This is proportional to the mass, so if you change the mass by a factor of "a", the gravitational potential energy will change by the same factor of "a".
-- If the velocity is horizontal, then gravitational potential energy doesn't change. -- If velocity is vertical and upward, gravitational potential energy increases at a rate proportional to the speed. -- If velocity is vertical and downward, gravitational potential energy decreases at a rate proportional to speed.
The Potential energy decreases as r increases.
popiseed muffins rock!
It doubles. F=(Gm1m2)/r2 G=gravitational constant, m1= mass of one object, m2= mass of other object, r= distance between them, F=gravitational force (It also begins to exert double the force on other objects nearby.)
It decreases as the square of the distance.
