The phrase "physical assumption" is correct and usable in written English.
It refers to a belief or principle that is based on the physical or tangible aspects of a situation or concept. Example: The mathematical model used to predict the movement of the planets is based on several physical assumptions, such as the laws of gravity and the shape of the Earth's orbit.
Thus, instead of interpolation based on some physical assumption, we utilize a distance measure in the interpolation.
One scheme requires the help of the parameter registration committee and the other needs a stronger physical assumption of the voting booth.
An important feature of the model is a more physical assumption of continuity in the velocity and shear stress profiles at the gas liquid interface.
What's doing the work is the physical assumption that there is no macroscopic action at a temporal distance, that mechanisms in fact underlie apparent cases of direct action between temporally remote events.
The latter is based on the physical assumption that external sources of noise have finite correlation times, so that we are considering the external noise to be the zero correlation time limit of a colored noise process.
Unluckily, the generalized nonlocal continua theories are based (often tacitly) on the physical assumption of long-range particle interactions while the actual particle interactions are short-range on nanometer or angshort-range on
The result that the experimental termination rate coefficients can be reproduced with an a priori model with physically reasonable parameters supports the physical assumptions underlying that model.
Two physical assumptions were made for the modelling.
A dynamic model was established with several physical assumptions, and validated using relevant experimental results.
A second model reduction is therefore performed, based on physical assumptions.
For on Putnam's account, the truth of mathematical sentences no longer depends on physical assumptions about the actual world.
