Summary
DescriptionForce Field-Gravity Well Inter-relationship.png
English: A 2-D slice of a gravitational force vector field (left) is interchangable with a 3-D gravity well (right), with the z-axis showing energy (potential). The gradient at any point on the potential surface is the negative force vector in the x-y plane. Each x-y point of the force vector function has a one-to-one correspondence to the x-y point on the scalar potential function, and vice-versa.
Note: Half of the field has been cut away for clarity.
