Hooke's Law - Direction Variation Application

New Review

Get a direct stretch from a spring. The presentation shows how Hooke's law uses direct variation. Scholars see how to calculate the spring constant for a spring given a stretch distance and a force. Individuals then use the spring constant to find the stretch for a different force and determine whether the distance is reasonable.
