Special relativity can be used to study an object in physical events.

That is Einstein's theory of relativity.
Absolute motion is motion relative to a presumed absolute reference frame. Special Relativity posits that the laws of nature are perfectly symmetrical with respect to any inertial reference frame. This implies that there is no absolute reference frame, and that absolute motion is a useless concept.
Rest and motion are relative terms because an object's state of rest or motion is defined in relation to another object. An object can be at rest relative to one object but in motion relative to a different object. This concept is based on the principle of relativity in physics, as described by Galileo and later by Einstein in his theory of special relativity.
According to the Theories of Relativity, time is NOT independent of the reference frame.
In an inertial frame of reference, an object will fall if placed in air unsupported due to the force of gravity acting on it. The room's upward motion is irrelevant in this scenario because gravity pulls the object downward regardless of the room's movement. As long as the room's motion is constant, objects inside it will still experience the usual effects of gravity.
It says that the speed of light in a vacuum measured in any inertial frame of reference is equivalent to the speed of light in a vacuum measured in any other inertial frame of reference.
It is exactly 22354786 minutes in duration in the reference frame of the person measuring the passage time (as described by special relativity).
Rest and motion are relative terms, meaning they are defined in relation to a particular frame of reference. An object at rest in one frame of reference may be in motion in another frame. This concept is a key aspect of Einstein's theory of relativity.
The object that serves as the reference point for determining motion is known as the frame of reference. It is used to describe the motion of an object relative to another object or observer. The choice of frame of reference can affect how motion is described and analyzed.
You could be moving in one frame of reference but not in another due to the concept of relative motion. Motion is always relative to a specific frame of reference, so if one frame is moving in relation to another, an object could appear to be stationary in one frame and moving in another. This is a key principle of Galilean relativity.
Any moving object can be redefined as a frame of reference at rest, from which all other moving frames can be measured. That's a fundamental precept of Relativity. It's motion is defined only in relation to some other object from which the motion is measured, so reselection as the rest frame is necessary, but once established as a rest frame, it is (for the purpose of measurement) no longer considered to be in motion. Since everything is moving in relation to everything else, any frame can be selected as the frame of reference at rest, with all other motion measured relative to it.
