Hooke Law: Displacement of the spring and restoring force

A spring is deflected by the value \( y \). This deflection results in a restoring force \( F \).

A Hooke's spring is an elastic mechanical spring that builds up a restoring force \( F \) when stretched or compressed. For a Hooke's spring, the restoring force depends on the deflection \( y \) and increases linearly with the deflection:

Here, \( D \) is a spring constant that indicates how stretchable a spring is.
