Conservative Vector Fields

A conservative vector field describes a force or field in which the work done between two points depends only on the initial and final positions. For a ball moving in Earth’s gravitational field, gravity performs work determined by the difference in height, regardless of whether the ball moves vertically or follows a curved trajectory.

Imagine throwing a ball upward from a certain height.

During its motion, the ball may travel straight up and down or follow a curved path. As the ball moves through Earth’s gravitational field, the work done by gravity depends only on the initial and final heights, not on the path taken. This property is called path independence.
