Marking points

  1. 1 Select the statement that the spring returns to its original length when the force is removed.

Full-mark answer

The spring will return to its original length when the force is removed.

Why this answer loses marks

The force on the spring causes it to change shape.

This only describes deformation. It omits the essential elastic property of returning to the original length when the force is removed.
