Pull. Measure.
Find the pattern.

Observe deformation, collect load–extension evidence, calculate spring constant and locate the limit of proportionality.

Investigation 1

Change an object’s size or shape

A force may stretch, compress, bend or twist a solid.
Apply a force
Investigation 2

Carry out a load–extension experiment

Measure original length, add loads gradually, calculate extension and record a table.

Investigation 3 · Supplement

Plot, interpret and calculate

Find k = F/x in the proportional region and identify the limit of proportionality.
