springs summary

The video tutorial explains the concept of spring force, which is the force exerted by a spring on a block when stretched. It introduces the formula F = -kx, where F is the spring force, k is the spring stiffness, and x is the displacement from the spring's unstretched length. The negative sign indicates the direction of the force, which opposes the direction of displacement. The tutorial also covers the units of measurement for these variables and provides an example to illustrate the concept.

Define the term 'displacement' in the context of spring mechanics.
