Use the example of a particle in a constant force field to illustrate a (constant) differential 1-form. Then use the marginal costs of acquiring/relinquishing assets from an investment portfolio to illustrate a (constant) differential 1-form. Went on to explain how a differential 1-form can be viewed as an infinite collection of vectors, one vector associated to each point in space. Finished by introducing the integral of a 1-form on a connected, oriented 1-dimensional region as the "work done" in moving a particle from the initial boundary point of the region to the final boundary point of the region.
