Energy Types & Conservation (Core Physics)

Course Overview

The Energy Types & Conservation (Core Physics) course gives learners a clear, exam-focused mastery of energy in IGCSE and O Level Physics—covering the major forms of energy, the key comparisons between gravitational potential energy and kinetic energy, and the central rule of physics: energy cannot be created or destroyed, only transferred and transformed. Learners will also build strong problem-solving ability in work, power, and the work–energy theorem—the exact skills needed to score consistently on structured and calculation questions.

Using structured explanations, multiple worked examples, exam tips, mnemonics, interactive quizzes, and high-quality LearnStalk explainer videos, learners will build fast recall, correct scientific vocabulary, and mark-scheme-ready reasoning. Whether you’re revising for mocks, preparing for finals, or strengthening your foundations for advanced physics topics, this course guides you step by step from core concepts to exam confidence.

What You Will Learn

• Identify and describe the major types of energy (potential, kinetic, electrical, thermal, chemical, nuclear, radiant/light, sound) using correct definitions and examples.
• Calculate gravitational potential energy using GPE = mgh and explain how height, mass, and gravity affect stored energy.
• Calculate kinetic energy using KE = ½mv² and explain why speed has a bigger impact than mass (because of v²).
• Distinguish clearly between potential energy vs kinetic energy and apply the comparison to common exam scenarios (falling objects, slopes, roller coasters, pendulums).
• Apply the law of conservation of energy to explain energy transfers in ideal and real systems, including losses due to friction and air resistance.
• Calculate work done using W = Fd and connect work directly to energy transfer in physical processes.
• Calculate power using P = W/t and P = E/t, and interpret what power means in real-life performance.
• Use the work–energy theorem to link net work to changes in kinetic energy: W(net) = ΔKE, and solve exam-style motion questions.
• Write correct energy transformation chains for everyday systems (hydroelectric dams, engines, bulbs, kettles, speakers, braking systems, solar panels) including useful vs wasted energy outputs.
• Solve mixed exam problems by choosing the correct formulas, showing clean working, and avoiding common traps in units, squared terms, and loss statements.

Why This Course Matters
Many learners lose marks in energy questions not because the topic is hard, but because they confuse work vs energy vs power, forget how to set up conservation equations, or fail to mention energy losses in real systems. In IGCSE/O Level exams, energy questions regularly test your ability to explain transfers, write transformation chains, and calculate using standard formulas. This course solves that problem by giving you a connected map of energy concepts and a reliable exam method—so your answers become accurate, fast, and confident.
