Why at a constant speed if an object changes its direction it is considered to be acceleration?

Acceleration is a direction plus a speed. If either changes then the acceleration changes.

Why is circular motion an example of constant acceleration?
Actually it isn't. In circular motion, even if you assume a constant speed (the simplest case), acceleration is towards the center. Therefore, the direction of the acceleration changes all the time - and therefore, the acceleration changes all the time.
Direction of an object's velocity changes uniformly frome east to north What is the direction of acceleration?
North-west. More specifically, as the object's velocity direction changes uniformly from east to north, the acceleration and force producing this acceleration are both constant and changing direction uniformly from north to west.
Can a direction of velocity of an object reverse at constant acceleration?
Sure. A pendulum and a park swing both have constant acceleration due to gravity, and the direction of their velocity changes over and over again until they're stopped.
Is it possible for a body to have an acceleration when moving with constant velocity?
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
Is it possible that the velocity of a body changes and its acceleration remains constant?
The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.
What changes as an object moves with a constant acceleration?
During constant acceleration, either the object's speed changes at a constant rate, or the direction of its motion changes at a constant rate, or both.
Why is it an object can accelerate while travelling at constant speed but not at constant velocity?
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.

When velocity is increasing can acceleration remains constant?
Acceleration is any change in velocity. Velocity is made up of a magnitude (the speed), and a direction. Velocity can change if the speed increases, if it decreases, or if the direction changes. For example, when a car goes around a curve, you feel the force of the acceleration.
Can an object moving at a constant speed have acceleration?
Acceleration is defined as the change in velocity over a given time period. Velocity is a vector quantity: it includes speed and direction. That being said, you can accelerate an object without changing its speed by simply changing its direction. A body moving along the circumference of a circle its speed may remain a constant, but its velocity will not be a constant since its direction of motion continuously changes, since the velocity changes it has an acceleration.
Does the acceleration of a body moving in circular path remain constant?
If the speed of the object doesn't change, then yes.
Can you go around a curve with constant velocity?
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.
example of a change in acceleration while travelling at constant speed?
An example of a change in acceleration while traveling at constant speed can be observed when a vehicle moves in a circular path or takes a turn. Although the speed remains constant, the direction of the motion changes, which results in a change in velocity. Since acceleration is the rate of change of velocity, this alteration in direction causes a change in acceleration, even when the speed is constant.
