... up to the top of the roof which is twice as high...8 m tall. So now find his GPE. Notice...in each case, if you release the object, it will move, so as it moves down, the GPE gets converted to KE. Any object that is elevated has GPE. Any object that is at its lowest possible point has no GPE ...

Scalar Field Theories with Screening Mechanisms
... which are known as the Vainshtein radii. As r → 0 then g → 0 also. This means that the force must become weaker than gravity for the equation of motion to be satisfied. This model therefore does not depend on the size of the density of the object unlike when using the chameleon screening mechanism. ...
