GCSE Physics (9-1) - GCSE Physics - Elasticity, Spring Constant & Hooke's Law | Force Extension Graphs (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. Deformation of Objects * How applying forces can compress, stretch, and bend objects. * The difference between elastic and inelastic (plastic) deformation. 2. Hooke's Law and the Spring Constant * The concept of extension in stretched objects like springs. * The direct proportionality between the force applied and the extension. * The equation for Hooke's Law (F=ke) and the definition of the spring constant (k). 3. Force-Extension Graphs * How to interpret a force-extension graph for a spring. * Identifying the linear region where Hooke's Law is obeyed. * Understanding the elastic limit (limit of proportionality) and what happens beyond it. *** CHAPTERS *** 0:00 Introduction 0:23 Applying Force and Deformation 1:13 Elastic and Inelastic Deformation 1:56 Extension and Proportionality 3:14 Hooke's Law and the Spring Constant 4:21 Force-Extension Graphs 4:58 The Elastic Limit *** PLAYLISTS *** https://youtube.com/playlist?list=PLidqqIGKox7VzYfPIVt8T09xOLNcolCe4&si=8JmDajxjtba6rdc3 https://youtube.com/playlist?list=PLidqqIGKox7UZ3mWhbHv2aA_1vnbsfRPq&si=q3hEKdA4v7kbfwMe https://youtube.com/playlist?list=PLidqqIGKox7XPh1QacLRiKto_UlnRIEVh&si=orIUwL3o2jOoiYjT https://youtube.com/playlist?list=PLidqqIGKox7X5UFT-expKIuR-i-BN3Q1g&si=DcihOwUkd9oWbbdp https://youtube.com/playlist?list=PLidqqIGKox7WeOKVGHxcd69kKqtwrKl8W&si=Y8MsO-FK948jnxpS https://youtube.com/playlist?list=PLidqqIGKox7UVC-8WC9djoeBzwxPeXph7&si=-7i5Iq7yOeJrhtu6 https://youtube.com/playlist?list=PLidqqIGKox7VKJD2WxRhoKaI6JGLVean8&si=NH_Q1ujhVgACM2FU #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
