The phrase "a law of motion" is correct and usable in written English.
It can be used in contexts related to physics, particularly when discussing the principles governing the movement of objects.
Example: "Newton's first law of motion states that an object at rest will remain at rest unless acted upon by an external force."
Alternatives: "a principle of motion" or "a rule of motion".
Factor in the matter of velocity, however, and we have a law of motion that might make Isaac Newton smile.
Hume considers Newton's second law of motion (F = ma) in the Enquiry, section 4, part 1 (EHU 4.13; SBN 31): "Thus, it is a law of motion, discovered by experience, that the moment or force of any body in motion is in the compound ratio or proportion of its solid contents and its velocity ….
After discovering the laws of motion, Newton obsessively sought a primal ur-religion out of which current beliefs developed; had he succeeded in discovering such a law of religious motion, one crucial element would have been vegetarianism.
"It's a great activity for our laws-of-motion study...Just hearing the students talk among themselves about which rocket will go higher, seeing that learning happening right in front of you, is impactful".
Our choice guaranteed that the biological motion could not be associated to a unique path shape nor to a unique law of motion.
A load is applied when the medium is at rest and moves according to a given law of motion (Fig. 12).
The first claim supposes what Descartes denies — that there is empty space (Principles II:10 12, AT 8A:45–47, CSM 1 226 28) — and the second contradicts a Cartesian law of motion that falls immediately out of our idea of God (Principles II:36 37, AT 8A 61 63, CSM 1 240 41; Nadler 1987).
Indeed, he argues that modern capitalism has an internal law of motion that leads, not inexorably but generally, toward less equal outcomes.
Deflection occurs because, in accordance with Newton's first law of motion, a parcel moving in a certain direction will retain the same motion unless acted on by an exterior force.
As a consequence of his first law of motion, Descartes insists that the quantity conserved in collisions equals the combined sum of the products of size and speed of each impacting body.
Thrust is a mechanical force generated by propulsion, as explained by Newton's third law of motion: if a working fluid is accelerated in rear direction, the aircraft is accelerated in the opposite direction.
