Explanation:

Answer 2

Explanation:

Mass is a feature of physical (really existing) objects. Force is feature of interactions and that means that force is not a feature of an object. It can charachterise objects in a given situation.

Imagine some closed system. It may contains subsystems that are interact and interchange energy. That means there can be many forces which are changing in time inside described closed a system but its mass will be constant. That means that a mass is a feature of any existing an object (measurable phycical object). That means that mass is a fundamental feature. But all that is present in relative to accepted agreements about terminology of course. It is useless to argue
