Mass
Engineering Fundamentals · Last updated: July 30, 2026 · How this entry was written
Definition: The amount of matter in a body, which determines its inertia and its response to applied forces.
Example in context
“The mass of each component must be recorded so the total weight of the assembly can be checked.”
“Montajın toplam ağırlığının kontrol edilebilmesi için her parçanın kütlesi kaydedilmelidir.”
Where engineers use it
Mass is a base quantity in every dynamic and structural calculation; engineers track it in weight budgets, inertia computations, and vibration models, distinguishing it carefully from weight, which depends on gravity.
Practice: can you use “Mass” at work?
A satellite project has a strict launch mass budget. Explain how you would track the mass of each subsystem and why mass differs from weight in orbit.
Show a model answer
“The component's mass is measured in kilograms, not newtons.”
