Final answer:
The area under a field-versus-position curve represents the work done by a force.
Step-by-step explanation:
The area under a field-versus-position curve represents the work done by a force. In physics, work is defined as the product of force and displacement. When the force is not constant, the area under the curve is divided into strips, each having an average force. The total work done is the sum of the work done by each strip, which is equivalent to the total area under the curve.
