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.

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.
When velocity is negative and acceleration is zero what happen the object in the 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.
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
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.

The acceleration of a body is opposite in direction to its velocity?
If that happens, the body's speed will decrease.
When does something accelerate in the direction opposite to its direction of motion?
If the object is speeding up, the acceleration is in the directionary of the velocity.
Is it possible of a body to have its velocity and acceleration pointing in opposite direction plot a velocity-time graph if yes?
Yes, it is possible. For example, if you through an object up, its velocity would initially be in the "up" direction, but its acceleration would be in the "down" direction.
