Question

"Isolated object" - what kind of examples would be of an isolated object? And please explain why.

In context: "An object that has no conducting path to earth is referred to as an isolated object"

Answer 1

A system in which the only forces that contribute to the momentum change of an individual object are the forces acting between the objects themselves can be considered an isolated system. ... For such a collision, total system momentum is conserved.

Answer 2

This simply means any object whether conducting or non-conducting if kept isolated i.e.,not in contact with Earth so that its charge cannot get transferred to it is called isolated object.
