Is gravitational potential energy of body by $mgh$ negative?

The two expressions have different locations for their energy zero points, that is why they disagree. $mgh$ is zero at wherever you have set $h=0$ to be with your coordinate system. Typically that is &...

Is gravitational potential energy of body by $mgh$ negative?

The key here is that it is the difference in potential energy that is important and this yields the same result in magnitude and sign, using using either equation. The potential energy is obtained by ...
