Question

he physically meaningful quantity work. Clearly,
ential energy so defined is undetermined to within an
itive constant. What this means is that the actual value
otential energy is not physically significant; it is only
difference of potential energy that is significant. We can
ays add an arbitrary constant a to potential energy a
y point, since this will not change the potential energ
erence:
+ a)-(UR + a) = Up - UR
it differently, there is a freedom in choosing the poi
potential energy is zero. A convenient choice is to ha
static potential energy zero at infinity. With this choi
in noint Rat infinity, we get from Eq. (2.2)

Answer 1

Answer:

hi

Explanation:

I am really not able to understand your question, define it clearly

Answer 2

Potential energy is closely linked with forces. If the work done by a force on a body that moves from A to B does not depend on the path between these points, then the work of this force measured from A assigns a scalar value to every other point in space and defines a scalar potential field.
