# Vector calculus facts for kids

**Vector calculus** is a branch of mathematics that investigates vector fields and how they change over time. Vector calculus usually studies two- or three-dimensional vector fields, but can be used in higher dimensions, too. It is a part of the study of multivariable calculus. Vector calculus is useful in physics and engineering because of how it can look at *electromagnetic* and *gravitational* fields.
