Mass-Energy Relationship and Units

The video tutorial covers the concept of nuclear structure and the unified atomic mass unit. It explains the energy equivalence of one atomic mass unit using Einstein's mass-energy equivalence principle, E=mc^2. The tutorial includes detailed calculations of energy in both joules and mega electron volts, emphasizing the conversion process between these units. The importance of understanding these concepts for solving numerical problems in physics is highlighted.

What is the primary unit used to measure the mass of atomic and subatomic particles?
