What is the name of the physical quantity for which the formula v = v0 + -at

is the formula v = v0 + at
v0 – initial speed
a – acceleration,
t – time
in our case, v = v0-at, our acceleration is negative, which means it slows down this indicates that the speed is slowing down.
This suggests that v = v0-at is a uniformly accelerated rectilinear speed answer: v = v0-at – uniformly accelerated rectilinear speed
