inertiaaliviitekehystä
Inertiaaliviitekehys is a Finnish term that translates to inertial frame of reference in English. An inertial frame of reference is a fundamental concept in physics, particularly in classical mechanics. It is defined as a frame of reference in which Newton's first law of motion, also known as the law of inertia, holds true. This means that an object at rest will stay at rest, and an object in motion will continue in motion with the same speed and in the same direction, unless acted upon by an external force.
In simpler terms, an inertial frame of reference is one that is not accelerating. If you are
The concept of inertial frames is crucial because the laws of physics, as formulated by Newton, are
Non-inertial frames, on the other hand, are accelerating frames of reference. In these frames, fictitious forces,
