(where Delta Velocity is change in Velocity or V2 - V1)
Yes, decreasing acceleration could still be positive, which yields an increase in velocity (speed).
Velocity is the rate of change of position, and acceleration is the rate of change of velocity. As long as the acceleration is positive, then velocity is increasing. If acceleration becomes negative, then velocity is decreasing.
=======================
I second that accelerated motion !
Even if the acceleration is petering out, as long as it's still more than zero,
the speed can be increasing.
By the way ... you can have a big solid acceleration, and it doesn't mean that the
speed or the size of the velocity has to be increasing.
Or even changing.
But that's another story.
Yes, that would be true.
yes, if the acceleration is in the opposite direction of the velocity.
Anytime an object is slowing down, its acceleration is in the opposite direction to its velocity.
Yes, velocity and acceleration can point in the opposite direction to each other. This is because neither one depends on the other. When velocity and acceleration are opposite each other this results in slowing down, for example when you hit the break on your car.
It accelerates in the opposite direction. Its velocity increases in the opposite direction to the direction that has been assigned positive.
Deceleration can be seen as opposing the velocity direction.

Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they are in opposite direction. It does not matter if the motion in linear or anfular.

When acceleration is opposite to (against) the direction of motion, the magnitude of the velocity decreases, meaning that the object slows down. An example is the application of the brakes to slow or stop a car. During the time that the pressure remains on the brake pedal, the car's acceleration is negative ... meaning opposite to the direction of motion ... and the car's speed is decreasing.

Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
If you are decreasing velocity, you are undergoing negative acceleration.
If that happens, the body's speed will decrease.
