Elasticity & Hooke's Law! 🏗️ Young Modulus & Graphs ( JAMB Physics)

Описание: Can you calculate the Young Modulus of a wire in under 60 seconds? 🚀In this video, we break down Elasticity for the JAMB 2026 UTME. Whether it's a spring in a car suspension or a wire holding up a bridge, the physics of stretching is a high-yield area in the Mechanics syllabus.We move beyond simple "spring" questions and dive into the properties of materials—explaining why some things snap while others stretch forever.🎯 What You Will Learn in This Lesson:Hooke’s Law: Understanding $F = ke$ and why it only works within the Elastic Limit.Spring Constant ($k$): How to find it from a graph or a table of values.Elastic Potential Energy: Calculating the work done in stretching a material using $W = \frac{1}{2}Fe$ or $W = \frac{1}{2}ke^2$.Stress, Strain & Young Modulus: * Tensile Stress: $\frac{Force}{Area}$.Tensile Strain: $\frac{Extension}{Original\ Length}$.Young Modulus ($E$): The ultimate measure of a material's stiffness.Energy Stored in a Wire: Mastering the formula $W = \frac{EAe^2}{2L}$.

🚀 Why This Video is Your Secret Weapon:Strictly 2026 Syllabus: Focused on the "Properties of Matter" section of the JAMB brochure.CBT Conversion Hacks: Learn why you MUST convert extension to meters before calculating energy or Young Modulus.Solved Past Questions: We solve real JAMB questions on springs in series vs. springs in parallel.🔔 JOIN THE 300+ SCORE SQUAD!Physics is easy when you understand the "why" behind the "how."
