No, Einstein proved that all inertial frames are equally valid references. You don't have to assume it's "fixed in place" or even know exactly how it's moving relative to any other frame as long as you know how the measured object is moving relative to the chosen reference frame.
A frame of reference in physics, may refer to a coordinate system or set of axes
Acceleration cannot be measured directly. An accelerometer, therefore, measures the force exerted by restraints that are placed on a reference mass to hold its position fixed in an accelerating body. Acceleration is computed using the relationship between restraint force and acceleration...

we need a fixed reference point to describe the position of a body
Yes, movement can be measured in reference to something assumed to be fixed in place. This is known as relative motion, where the movement of an object is determined by comparing it to another object or reference point that is considered stationary.
It is the process of a change in position relative to some fixed point of reference.
It is because many things are measured with reference to a fixed point: it space or time. This point is called a reference point or origin.
In Newtonian terms, yes but otherwise no. Molecules are always in a state of vibration. Also, the term "fixed position" assumed a fixed frame of reference and Einstein's work showed that there is no such thing.
Resistance is measured in ohms.
The definition of a true compass bearing - A true bearing is measured in relation to the fixed horizontal reference plane of True North, that is using the direction towards the geographic North Pole as a reference point.
The definition of a true compass bearing - A true bearing is measured in relation to the fixed horizontal reference plane of True North, that is using the direction towards the geographic North Pole as a reference point.
The vertical axis gives the distance of an object from a fixed point - the point of reference - after a time, as measured on the horizontal axis.
The definition of a true compass bearing - A true bearing is measured in relation to the fixed horizontal reference plane of True North, that is using the direction towards the geographic North Pole as a reference point.
money income is fixed
LOCAL TYM OF A PLACE IS FIXED WITH REFERENCE TO THE APPARENT MOVEMENT OF THE SUN. eg. where the sun is over head in the sky it is mid day or 12 noon..
