What happpens to a car moving at a constant speed as it turns a corner?
The car undergoes a change in velocity. It accelerates (and does so at a constant rate - if the rate of turn is constant) in the direction of the turn. The speed is constant, but the direction the car is going changes at each instant in time because it is turning. And because it is changing direction, that means its velocity is changing (because velocity is speed plus a direction vector).
It is possible for a body to have acceleration when moving with costant velocity and constant speed?
Physical experiments give the same result, no matter how an object is moving (assuming it is moving at a constant speed). Therefore, there is no way to measure "real" or "absolute" speed. Nor is there any way to define it. Physical experiments give the same result, no matter how an object is moving (assuming it is moving at a constant speed).

Why an object moving in a circular path at a constant speed is undergoing acceleration and has a force excert on it?
-- An object with no net force on it continues moving at constant speed in a straight line. If it's not moving in a straight line, then there must be net force acting on it. -- "Acceleration" is the word for the situation where either speed or direction of motion changes. Even if speed is constant, acceleration is present if the direction is changing.
for an object to travel at a constant speed, there is a need for equal force that needs to act in favour of the object. But there are quiet a few factors that can stop an object from for a constant speed, that are friction, drag (including air resistance or moving fluid) which acts against the moving to slow it down.
It's possible, but not necessary, that a particle moving with constant speed has zero acceleration. In order for acceleration to be zero, it's also necessary that the particle be moving in a straight line. An object moving with constant speed around a curve has acceleration. "Acceleration" does not mean "speeding up".
Of course. In fact, in order to have constant velocity, it must have constant speed. What you really want to know: Can a body have changing velocity when it has constant speed ? The answer to that one is also "yes", for example when it is moving in a circle, the speed is constant but the velocity is changing all the time (in direction).
It depends on which direction you are resolving the acceleration from. If you use the original direction of the car as it turns it is decelerating as the speed it is moving in that direction is decreasing. If you resolve from the direction which the car will be going towards then it is accelerating as its speed in that direction is increasing.
Constant speed is movement at a fixed (constant) distance per unit of time. The same amount of distance is covered by the object in the same amount of time at each measurement of that same interval. An example of an object moving at a constant speed might be an object in orbit. Something up their above the drag of the atmosphere will move at a constant speed, and will continuously move around the earth at…
