Work done by a variable force and Hooke's law - Physics

This video tutorial explains how to calculate the work by a force when the force is variable and changes with position. Hooke's law that defines spring force is also explained. The video also discusses the concept of work as area under the force-position graph. Solved examples are given to boost understanding of the concepts presented. 0:00 Introduction 0:44 Idea & equations 2:23 Hooke's law and spring force 6:12 Work as area under F-x graph 7:38 Solved problem 1 9:03 Solved problem 2 Other related videos on work: https://youtu.be/4ZJb-bFALRw https://youtu.be/qYYUp5HOSm8
