## Main Question or Discussion Point

According to the eq. U=mgh the gravitational potential energy should keep increasing with height. But it actually reaches zero at infinity.

At what point does the g.p energy start decreasing when going away from earth?

Why does this eq. seem to contradict -GMm/r where g.p energy decreases with distance?

How does one solve mgh for infinity?

Thanks in advance.
