WebA gravitational field can be defined using Newton's law of universal gravitation. Determined in this way, the gravitational field g around a single particle of mass M is a vector field consisting at every point of a vector pointing directly towards the particle. WebJan 22, 2024 · In this article, we shall discuss the concept of the gravitational potential at a point in a gravitational field. It is defined as the work done in bringing the unit mass from infinity to that point without acceleration. Considering magnitude only. V G = W / m It is a scalar quantity. It is denoted by V. Its S.I. unit is J kg -1. WebWe define the potential at a point in a field as the energy per unit mass stored by placing 1kg at that point in the field. We can get equations for potential using this definition. For a field due to a (point or spherical) mass M, we have: EG = − GMm r And so the potential, V , is given by: V = − GM r A few points to make: cos\u0027è la prosocialità
