A student investigates how a thick elastic cord stretches under different loads.

Diagram showing a vertical clamp stand holding a thick elastic cord. The top of the cord is clamped firmly. At the bottom of the cord, a horizontal pointer is attached, pointing towards a vertical metre ruler clamped next to it. Below the pointer, a weight hanger hangs vertically, allowing slotted weights to be added.

The student first hangs the weight hanger from the bottom of the elastic cord so that it is straight but not stretched, and records the initial position of the pointer.

Describe how the student can determine the extension of the elastic cord each time a new weight is added to the hanger.
