inertialisessa
Inertialisessa is a Finnish term that translates to "in the inertial frame" or "inertially" in English. It refers to a reference frame in physics where Newton's first law of motion, the law of inertia, holds true. In such a frame, an object at rest will remain at rest, and an object in motion will continue in motion with the same velocity, unless acted upon by a net external force.
Inertial frames are fundamental to classical mechanics. All inertial frames are in uniform relative motion with
Conversely, a non-inertial frame is one that is accelerating. In a non-inertial frame, objects may appear to
The concept of inertial frames is crucial for formulating and applying physical laws, particularly those related
