Taustsüsteemidega refers to the concept of reference frames in physics. A reference frame is a set of physical objects or coordinates that are considered to be at rest. When observing the motion of an object, it is always necessary to specify the reference frame relative to which the motion is being measured. Different reference frames can lead to different descriptions of the same motion. For example, an object moving at a constant velocity in one reference frame might appear to be accelerating in another reference frame that is itself accelerating.

In classical mechanics, two types of reference frames are commonly distinguished: inertial and non-inertial. An inertial reference frame is one in which Newton's first law of motion (the law of inertia) holds true. This means that an object at rest will remain at rest, and an object in motion will continue in motion with constant velocity, unless acted upon by a net external force. Inertial frames are either at rest or moving with constant velocity relative to each other.

A non-inertial reference frame is one that is accelerating. In such frames, fictitious forces, such as the centrifugal force and the Coriolis force, appear to act on objects. These forces are not real forces in the sense that they are not caused by interactions between objects, but rather by the acceleration of the reference frame itself.

The concept of reference frames is fundamental to understanding many areas of physics, including kinematics, dynamics, and relativity. Einstein's theories of special and general relativity further expanded upon the idea of reference frames, introducing the concept of spacetime and demonstrating that the laws of physics are the same in all inertial reference frames. The choice of reference frame can simplify the analysis of a physical problem, and understanding the relationship between different reference frames is crucial for accurate scientific description.
