Consider a 5-kg object interacting gravitationally with the earth. Imagine that we set up a standard reference frame with the z axis pointing vertically upward. If the interaction's potential energy when the object is at z = 5 m is -50 J, what is the approximate z-position of the object when it is at its reference separation from the earth?© BrainMass Inc. brainmass.com March 4, 2021, 8:06 pm ad1c9bdddf
What they mean by "reference separation" is that point where the potential energy is zero. The potential energy is of the form:
V(z) = mg z + c
where c is some constant which ...
A detailed solution is given. Potential energy and gravitational pull is examined. The z-position approximation for the separation from the earth is determined.
