What is another word for rotational inertia?
Pronunciation: [ɹə͡ʊtˈe͡ɪʃənə͡l ɪnˈɜːʃə] (IPA) 
Rotational inertia refers to the resistance of an object to a change in its rotational motion. It is also known as moment of inertia. The term can be a mouthful to say, and if one needs to use different words to convey the same meaning, several options are available. For example, one could use the term angular momentum, rotational mass, or even rotary inertia. In the field of physics, the concept is essential in understanding how objects rotate about an axis. Different shapes and structures have varying levels of rotational inertia. Therefore, it is crucial to determine this property when studying the motion of objects.
