Grade 11 Science: How to Use AI to Master O/L Physics Topics
By Samisa Abeysinghe, CEO, Idasara Academy
Revise O/L physics one syllabus chapter at a time: read the free theory page for that chapter, test yourself on its revision page, then ask the AI Study Coach about the step you got wrong. The physics in O/L Science is spread across chapters of the NIE Grade 10 and 11 Science syllabus, and the steps below take them in syllabus order, Grade 10 first. This page is about learning the physics. For how the exam paper is set out and marked, read the O/L Science exam-readiness guide.
Where should I start?
Find out which chapters you are weakest in before you read anything. The free diagnostic quiz needs no account, and it tells you which topics to work on first. Start with those chapters below rather than at the top of the list.
Grade 10, Motion and Force: what do I need to be able to do?
Know the difference between distance and displacement, and between speed and velocity, then work out acceleration and weight. Newton's three laws explain why things start, stop and turn. Read the Motion and Force theory page first. In every calculation, write the formula, put the numbers in, and finish with the unit — m/s, m/s² or N.
Grade 10, Energy: Heat, Light and Sound: how do the forms of energy connect?
This chapter is about energy changing from one form to another, and about the joule and the watt. When a question describes a device, name the energy it takes in and the energy it gives out. Read the Forms and Transformations of Energy theory page, then ask the AI Study Coach to give you a device and check your energy chain.
Grade 10, Electricity and Magnetism: how do I read a circuit?
Start with simple circuits: what current is, what a cell and a switch do, and why the lamps in a series circuit share one path. Draw each circuit before you answer a question about it. The Electricity and Simple Circuits theory page covers the Grade 10 part.
Grade 11, Electricity: Current, Voltage and Resistance: how do I use Ohm's law?
Grade 11 returns to electricity with numbers: V = IR, resistors in series and in parallel, and why household wiring is parallel. Use the "Test yourself" section of the Electricity revision page to check you can still do the Grade 10 part, then work the calculations. If you get one wrong, ask the AI Study Coach which quantity you should have found first.
Grade 11, Introduction to Electronics: what does each component do?
Learn what a diode, a transistor and a logic gate do in a circuit before you learn how they are built. Write the truth table for each gate from memory, then check it against the Electronics revision page.
Grade 11, Heat and Thermal Energy: how do I tell heat from temperature?
Temperature tells you how hot something is; heat is the energy that moves because of a temperature difference. Learn the three ways heat moves, then Q = mcΔT and latent heat. Read the Heat, Temperature and Heat Transfer theory page, and check the unit on every answer: J for heat, °C for temperature.
Grade 11, Waves and Sound: how are sound and light different?
Both are waves. Sound needs a medium, but light does not. Pitch follows frequency and loudness follows amplitude. Test yourself on the Waves, Sound and Light revision page. Then explain one difference between sound and light to the AI Study Coach in your own words, and ask it what you missed.
What do I do after each chapter?
Go back to the chapters the diagnostic quiz flagged, not to the ones you already know. Each chapter's free page links the next one in the syllabus. When you want a study plan and an AI Study Coach across every subject, compare the plans.
