Mass Defect and Binding Energy Concepts

Paul from Physics Hi explains how to determine the mass defect and binding energy per nucleon for an alpha particle. He describes the process of calculating the mass of a helium nucleus and its constituent protons and neutrons, highlighting the concept of mass defect and its conversion to binding energy using E=MC². The tutorial includes unit conversions and calculations to find the binding energy per nucleon.
