Mass defect and binding energy

Mass defect and binding energy

The mass of a nucleus is slightly less than the total mass of its separate protons and neutrons. This missing mass is called the mass defect, Δm\Delta mΔm, and it shows that some mass has been converted into energy.

Step-by-step lessons on AQA A Level Physics Mass and energy (A-level only). Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
