CIE A-Level Physics Materials: Deriving spring equations

My channel has moved to a branded account! Check me out at The Flipped Guy, at https://www.youtube.com/channel/UCtbltzlVlMneodmLZzteFwg In this optional lecture, I show you how we can mathematically prove the equations to find the equivalent spring constant of springs in series and parallel. For my students, you do not need to know or understand this content for your CIE A-Level, however, I do recommend watching as it shows you how we can use and manipulate equations to derive new equations. This is a skill that's applicable to a wide range of physics
