In my text book, the definition of the Gravitational Potential, V is defined as :" the gravitational potential of a point in a gravitational field is the work done per unit mass by the pull of gravity to bring a body from infinity to that point. "(adsbygoogle = window.adsbygoogle || []).push({});

Who make this definition ? As i know, infinity is a quite abstract concept, most of the time it causes confusion, hence, why physicist still choose to use "infinity" ? Is there any benefit they will get by using inifinity in the definition ?
