Tutorial title

Emphasis (what do students do?)

Links to materials

Relate magnitude of force to spatial rate-of-change of potential energy (separate versions of tutorial focus on topographic maps and electric potential diagrams)

Operationally define gradient of a scalar field; apply definition to relationship between force and potential energy
