Binding Energy Explained (intuitively) @zhelyo

Uploaded April 2026 | Updated September 2026, 3 weeks ago

Here is an intuitive explanation of binding energy for A level Physics.
This is video designed for A Level Physics for all exam boards including AQA, OCR A and B, Edexcel, International Edexcel, CIE Cambridge Syllabus, WJEC, Eduqas and similar courses such AP Physics, IB Physics etc.

It covers the concept of Binding Energy in Nuclear Physics. Hope it's useful! Please let me know if you think my analogy is not accurate.

I tried 3 MARKS from The Asian Physics Olympiad in India

Please note that I have seen and solved most of these questions at various parts of my teaching in the past, however I did not do any specific practice before I started filming other than opening up the papers. Please note that these are not official solutions and I am not affiliated with the exam board OCR. These fantastic questions are from OCR Physics A and please access their original paper here: Question 1 to 20: https://www.ocr.org.uk/Images/677416-question-paper-breadth-in-physics.pdf (OCR Breadth in Physics 2022) Questions 1 to 15: https://www.ocr.org.uk/Images/676906-question-paper-modelling-physics.pdf (OCR Modelling Physics 2022) Chapters: 00:00 EM Spectrum 01:20 Kirchoffs Laws 02:06 Refractive Index 03:22 Youngs Double Slit 05:37 Power, kinetic energy 07:19 Phase Difference 09:56 Resistors in Parallel 11:17 Internal Resistance 13:55 Moments and perpendicular distance 16:52 Current and number of electrons 18:16 Electric Motor and Efficiency 20:06 Polarisation 20:28 Youngs Modulus 23:19 Thermistor 23:45 Moments 26:29 IV Characteristics 28:17 Photoelectric Effect 28:39 Electron Energy, eV 29:08 Waves 29:55 Intensity 31:00 Scalars and Vectors 31:37 Absolute Uncertainty from Data 32:35 Motion Graphs 33:32 Net Force 35:11 Moments 36:13 2D Momentum 39:32 Specific Heat Capacity and Graphs 41:01 Assumptions of Kinetic Theory of Gases 42:00 Root Mean Square Speed 44:57 Simple Harmonic Motion and Energy 46:00 Units 46:30 Energy Levels 47:28 Diffraction Gratings and Dopplers Effect 53:52 Age of the Universe and Hubbles constant 55:56 Cosmological Principle$
