What is another word for inertial mass?
Pronunciation: [ɪnˈɜːʃə͡l mˈas] (IPA) 
Inertial mass can also be referred to as simply mass or gravitational mass. It is a property of matter that describes an object's resistance to acceleration when a force is applied. Other synonyms for inertial mass include rest mass, proper mass, and relativistic mass. Rest mass refers to the mass of an object when it is at rest, while proper mass takes into account any energy that the object may have. Relativistic mass is a concept in physics that states an object's mass increases as it approaches the speed of light. Inertial mass is essential in the field of physics, as it helps to explain the motion of objects and the forces that act upon them.
