Inertial Mass vs Dynamic mass

Mass

For systematic understanding of materials in a system we can define mass in two categories. Positive charge is assumed as inertial mass and negatively charged particles are assumed as dynamic mass.

Inertial mass of the system is almost same as total mass because negatively charged particles are very light and are meant to move fast with little energy. Since inertial mass has much more inertia so its linear motion in many cases is very small but it carries energy due to spin mainly. Reason is simple that when heavy particle receives energy then due to inertia it do not prefer to translate in space but to store energy in terms of spin. In normal cases it is mobile electrons which carry positive charge from one place to other.

Electrons are micro winds around the nucleus. In absence of electrons any material when placed in appropriate electromagnetic condition tend to shrink to decrease its volume. Super dense materials are created by removing a good number of electrons and then subjecting to suitable electromagnetic condition so that nucleus are moved closer to each other. Electrons are like air filled in between to make matter less heavy and suitable for humans. In future nano forms of objects can be sold to customers and when they open tiny box and put object outside then by absorbing electrons from the atmosphere it will expand to its normal size.
