Question

A 1.0 kg book initially at rest falls from a height of 1.5 mto the floor. A) Does the gravitational potential energy at the initial andfinal points depend upon the location of the origin of thecoordinate system? B) Does the change in gravitational potential energy dependupon the location of the origin of the coordinate system? A 1.0 kg book initially at rest falls from a height of 1.5 mto the floor. A) Does the gravitational potential energy at the initial andfinal points depend upon the location of the origin of thecoordinate system? B) Does the change in gravitational potential energy dependupon the location of the origin of the coordinate system?

Explanation / Answer

(a)  the gravitational potential energy at theinitial and final points depend upon thelocation of the origin of the coordinatesystem E(x)=E0+mg*f(x) (b)the change in gravitational potential energydoesn't depend upon the location of theorigin of the coordinate system E(x)=mg*f(x)   => E0 not present . f(x) is a function with respect to x
