Gradient: The gradient of a scalar field represents the rate at which the scalar quantity changes in space.
Contour lines: These are lines on a scalar field map that connect points with equal values of the scalar quantity being represented.
Potential energy: Potential energy is a scalar quantity that depends on an object's position or configuration within a force field.
