Module 10: Energy and its Conservation // L2: The many forms of energy (1/2)

📌 Module 10 | The Many Forms of Energy | Session 1 of 2 In this lesson we look at the many forms energy can take — kinetic energy in a straight line and in rotation, and the energy stored as gravitational and elastic potential energy — with fully worked examples. 🎯 Learning objectives — by the end of this session you will be able to: Recognise the different forms of energy and identify the energy transformations happening in a real situation Tell translational kinetic energy apart from rotational kinetic energy, and say which one an object has Calculate translational kinetic energy using KE = ½mv², with mass in kg and velocity in m/s Use KE = ½Iω² for rotating objects, and identify a body that has both translational and rotational kinetic energy at the same time Explain what potential energy is, and distinguish gravitational potential energy from elastic potential energy Calculate gravitational potential energy using GPE = mgh, and choose a reference level correctly Work out the sign of the work done by gravity as an object rises and as it falls (Wg = −mgh and Wg = +mgh) 📖 Covered: Changing forms of energy · Translational and rotational kinetic energy · Potential energy: gravitational and elastic · Work done by gravity, rising and falling · Reference levels · Multiple-choice questions, problem solving and a challenge question ━━━━━━━━━━━━━━━ 📂 All lesson files (summaries + worksheets + answer keys): https://drive.google.com/drive/folder... 💬 Telegram groups — join your grade: Grade 9 Advanced: https://t.me/+DTX15OmjSBMzZjVk Grade 10 Advanced: https://t.me/+UbX68kNnvu02YTc0 Grade 11 Advanced: https://t.me/+aJXHMjj8GoNlM2Vk Grade 12 Advanced: https://t.me/+5Zkl70n3i-sxZWE0 📩 Questions?
