What is another word for inertial reference frame?
Pronunciation: [ɪnˈɜːʃə͡l ɹˈɛfɹəns fɹˈe͡ɪm] (IPA) 
An inertial reference frame is a coordinate system that is used to describe the motion of an object relative to the frame of reference. It is used to measure the acceleration and velocity of an object, and it remains unaffected by the motion of an object in it. There are several synonyms for an inertial reference frame, including a non-accelerating reference frame, a uniform reference frame, and a Galilean reference frame. These terms all refer to a coordinate system that is considered to be observing an object that is not experiencing any forces or acceleration due to its own motion. Inertial reference frames are used extensively in physics to describe the motion of objects and their forces, and they play a crucial role in the development of our understanding of the universe.
