For example… The level of reference h refers.
Imagine a space where an object of the mass m = 1.0 kg on a table, the table height being 0.80 m. [We also assume that the extension of the object is negligibly small, so it can be assumed approximately as point-shaped. And occurring height differences are also so low that the falling acceleration g = 9.81 m/s2 can be assumed as constant.]
How great is the potential energy of the object [because of the situation in the field of gravity]?
Now you could answer…
Now you look out of the window and notice that the room is in a high-rise building and the room [more precisely: the floor of the room] is located 20 m above the floor of the surroundings around the high-rise. Now, instead of referring to the space floor, one could also refer to the ground and would suddenly come to another potential energy for the same object…
Now you realize that the house is on a mountain… See what is going on?
That was what I was looking for. Thank you.
Hm… Whether the air resistance or the coefficient of friction must be taken into account?
Oh yes, on which celestial body this takes place.
