The phrase "a reduction in speed" is correct and usable in written English.
It can be used when discussing a decrease in the rate of movement or operation, often in contexts related to vehicles, machinery, or processes.
Example: "Due to the icy conditions, there was a significant reduction in speed on the highway, causing delays for all drivers."
Alternatives: "a decrease in speed" or "a slowdown in speed."
They often necessitate a reduction in speed or a change of course.
If that is correct it is hard to argue against a reduction in speed so the train runs as fast as a Train à Grande Vitesse (TGV) in France".
The difference in rotation periods between 200-km-class and 100-km-class asteroids is believed to stem from the fact that large asteroids retain all of the collision debris from minor collisions, whereas smaller asteroids retain more of the debris ejected in the direction opposite to that of their spins, causing a loss of angular momentum and thus a reduction in speed of rotation.
The high cost of engine development and the likely thinness of the market, at least to start, make the engine a tricky balancing act for Aerion and the other supersonic aircraft aspirants, Boom and Spike, leading to a reduction in speed from initial plans.
As regards behavioural adaptation (BA), the results of the present road-side interviews of 360 car drivers indicate that most of them (83%) did not believe that they had reduced their speed because of the rumble strips, but that if they imagined any change it would be a reduction in speed (12.5%).
The Germans encountered some ice at around 10 00, which necessitated a reduction in speed to 24 kn.
Environmentalists say that a reduction in speeds makes sense but warn that there is no guarantee that ships would not revert back to full throttle once economic conditions improve.
The initial delay is caused by a reduction in swimming speed after the dark-light switch (see below sections "Swimming speed after a dark-light switch as a function of light intensity" and "Swimming speed after light stimulation as a function of the swimming direction").
They found that dazzle patterning could affect speed perception in humans, with high contrast patterns causing a reduction in perceived speed [ 18].
No genotype-dependent differences in raw average swimming speeds (Fig. 4A inset) were observed and both Dyrk1A+/− and their controls showed a reduction in swimming speed along the 60 s of the trial (MANOVA, "time interval": F(1 59) = 13.741, P<0.0001; Fig. 4A).
The overall effect is a reduction in the speed of near-surface winds, which Jacobson has calculated to be up to 8percentt slower in California.
