Work done by a Spring - Deriving Elastic Potential Energy

The video tutorial explores the physics of a spring-mass system. It begins with a problem statement involving a 1 kg mass on a spring, leading to questions about the spring constant and work done by the spring. Using Hooke's law, the spring constant is calculated. The tutorial then explains how to determine the work done by the spring using integral calculus, highlighting the concept of elastic potential energy. A graphical representation of Hooke's law is provided, illustrating the relationship between force and displacement. The tutorial concludes with a discussion on the directionality of work and energy in the system.
