The phrase "a fixed frame of reference" is correct and usable in written English.
It can be used in contexts discussing perspectives, viewpoints, or standards that remain constant in analysis or evaluation.
Example: "In scientific research, having a fixed frame of reference is essential for accurate measurements and comparisons."
Alternatives: "a stable point of view" or "a constant reference point".
This plate defines a fixed frame of reference.
No longer was there a single timeline, or a fixed frame of reference.
A list of positions and proper motions for such selected stars well distributed over the sky is called a fundamental catalog, and its coordinate system is a close approximation to a fixed frame of reference.
The hydrodynamics of the system are described from a fixed frame of reference or Eulerian view point and the energy and component flows are described from a moving frame of reference or Lagrangian view point.
The analysis is carried out in a fixed frame of reference and gas penetration is modelled as the bubble moves down the tube, which is long relative to its transverse dimension.
Since the direction of the centre of the Galaxy is well established by radio measurements and since the galactic plane is clearly established by both radio and optical studies, it is possible to determine the motion of the Sun with respect to a fixed frame of reference centred at the Galaxy and not rotating (i.e., tied to the external galaxies).
If you're in a particular, fixed frame of reference (like stationary on the Earth's surface), then anyone who goes in motion relative to you will move a larger amount through space, meaning they'll move a smaller amount through time.
Since the ball is thrown in the direction of the Earth's rotation, its angular velocity in the fixed frame of reference increases; it experiences an increased centrifugal force.
Conversely, if the ball is thrown from east to west, its angular velocity in the fixed frame of reference decreases; the resulting decrease in the centrifugal force causes the ball to be deflected towards the pole, again to the right of the direction of motion.
"I call it drift time.' It's not being in a fixed frame of work or routine.
The effect of the experimental limitations inherent in a wind-tunnel slipstream methodology: the presence of a stationary floor, reduced length of the model, limited test-section size and ground-fixed frame-of-reference are also investigated.
