The phrase "affects the motion of" is correct and usable in written English.
It can be used in contexts discussing physics, mechanics, or any situation where the influence on movement is being described.
Example: "The gravitational force affects the motion of the planets in our solar system."
Alternatives: "influences the movement of" or "modifies the trajectory of".
Earlier devices could not accurately capture the vocal cords' fastest movements; the new camera, which can shoot ten thousand frames a second, allows Zeitels to see precisely how a tumor affects the motion of a patient's vocal cords.
We show that the dynamic screening of the hole by the cluster electrons affects the motion of the photoemitted electron.
In this subsection, we estimate the lift-drag ratio RLD to investigate how efficiently the lift force affects the motion of the dust.
The response of the structure affects the motion of supporting soil and the movement of supporting soil influences the structural behaviour.
In particular, we consider two primaries revolving in a circular mutual orbit and two small bodies of equal mass, neither of which affects the motion of the primaries.
This episode perpetuated a popular myth that the Coriolis effect affects the motion of drains in the Northern and Southern Hemispheres.
If such a step also affects the motions of the FRET pairs in mutants Y274W-S96CCPM and Y108W-N200CCPM, it may obscure the P2 phase for these mutants.
More than 120 extrasolar planets have been discovered orbiting other stars, most of them huge bodies found because their gravity affected the motion of their stars.
Economists improve the realism of DSGE models by adding in "frictions" and "accelerators" that affect the motion of the ball after it is struck.
Splicing on a fresh film without affecting the motion of the part of the film being processed is handled by using a storage unit or reservoir.
Such forces have been looked for already, and if they affect the motion of the planets in the solar system, for example, they have to be enormously more feeble than gravity, otherwise we would have seen them already.
