Deceleration
negative acceleration
Its called VELOCITY.
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.

Inertia. Inertia applies to both increases and decreases in velocity.

either resistance or inertia
That's simply called a change in velocity. On the other hand, the rate of change in velocity - how quickly velocity changes - is called acceleration.
momentum (vector)
True
True
true
It decreases the terminal velocity of the parachutist.
Manning equation if the hydraulic radius decreases then the velocity decreases
