viittaamiskehyksestä
A viittaamiskehys, or reference frame, is a fundamental concept in physics and mathematics used to describe the motion of objects. It is essentially a coordinate system and a set of synchronized clocks that are used to measure the position and time of events. Without a reference frame, it is impossible to define quantities like velocity, acceleration, or displacement.
There are different types of reference frames. An inertial reference frame is one in which an object
The choice of reference frame can significantly simplify the analysis of a physical problem. For instance,
