WebMar 12, 2024 · 1. In physics, fields are generally just geometric objects that vary (in some vague sense of the word) from point to point. The simplest examples being scalar fields or tensor fields. – Eletie. Mar 12, 2024 at 20:36. 2. The terminology of "fields" in geometry/physics is very versatile. WebI'm studying for a physics final, and i'm still a bit confused on how to think about a source point vector, and the difference between source points and field points. In my understanding, field points do not vary over an integral, and source points do. However, in class, our discussion of the topics essentially ended there.
