Does an object that is moving in a linear path with an acceleration in the direction opposite to the motion have a decreasing velocity?

(where Delta Velocity is change in Velocity or V2 - V1)

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.

Can the velocity of object reverse direction when its acceleration is constant?
yes, if the acceleration is in the opposite direction of the velocity.
Can you cite an example in which the acceleration of a boby is opposite in direction to it's velocity?
Anytime an object is slowing down, its acceleration is in the opposite direction to its velocity.
Can velocity and acceleration point in opposite direction?
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.
When velocity is zero and acceleration is negative what happens to the object in motion?
It accelerates in the opposite direction. Its velocity increases in the opposite direction to the direction that has been assigned positive.
Can anything have an acceleration in the opposite diretion to its velocity?
Deceleration can be seen as opposing the velocity direction.
Can the velocity of object reverse direction when its acceleration is constant?
yes, if the acceleration is in the opposite direction of the velocity.
When angular velocity decreases the direction of angular acceleration is opposite to angular velocity .why?
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.

What is the example where acceleration is against the direction of motion?
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.

Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
What is the effect on accelerationif we decreasing velocity?
If you are decreasing velocity, you are undergoing negative acceleration.
The acceleration of a body is opposite in direction to its velocity?
If that happens, the body's speed will decrease.
