As an object slides across a rough horizontal surface, what happens to the object's gravitional potential energy with respect to the surface and speed?

Would't potential energy decrease at rest?

How can GPE decrease on a horizontal surface? The distance to the center of the Earth is the same, that is what determines GPE.
GPE does not change on the horizontal surface.

Would speed increase?
Answered by Priscilla
I know speed would increase when potential energy decreases but in this case its different. Therefore, if potential energy is remaining the same wouldnt speed remain the same too
