Grade 10 Physical Sciences | Mechanical Energy Explained | Calculations & Exam Questions

📚 *GRADE 10 PHYSICAL SCIENCES | MECHANICS: ENERGY* 🔥 Learn how to calculate *MECHANICAL ENERGY* step by step with Joy T Maths & Sciences! In this lesson, we focus on Mechanical Energy, Kinetic Energy and Gravitational Potential Energy, using easy explanations, formulas and a worked examination question. ✅ *WHAT YOU WILL LEARN:* 🔹 *1. Mechanical Energy* Define mechanical energy. Understand the relationship between kinetic and potential energy. Calculate mechanical energy using: *Eₘ = Eₖ + Eₚ* 🔹 *2. Kinetic Energy* Understand energy due to motion. Calculate kinetic energy using: *Eₖ = ½mv²* 🔹 *3. Gravitational Potential Energy* Understand energy due to an object's position. Calculate gravitational potential energy using: *Eₚ = mgh* 🔹 *4. Worked Examination Question* We solve a question involving a 0.5 kg stone thrown vertically downward at 12 m·s⁻¹ from a 50 m building. You will learn how to: ✅ Calculate the mechanical energy of the stone. ✅ Calculate gravitational potential energy at the bottom of a window. ✅ Determine the speed of the stone using conservation of mechanical energy. ✅ Apply formulas correctly in examinations. 🎯 *WHO SHOULD WATCH?* Grade 10 Physical Sciences learners following the South African CAPS curriculum, particularly those preparing for tests, examinations and revision. 🏆 *JOY T MATHS & SCIENCES* Excellence Through Knowledge and Character. 📖 We study, we pass! 👍 LIKE if this lesson helped you. 💬 COMMENT your questions. 🔔 SUBSCRIBE for more Physical Sciences lessons and worked exam questions. #Grade10PhysicalSciences #MechanicalEnergy #Mechanics #KineticEnergy #PotentialEnergy #Physics #CAPS #PhysicalSciences #JoyTMaths #SouthAfricanEducation
