Not necessarily. A counter example may be a communications geosync satellite which continuously changes its direction (it does not traveling on a straight line) but it is exposed to, and affects, no change in the centrifugal acceleration of earth gravity.

Yes, as stated before, velocity is a vector. Acceleration is a change in velocity. This requires an external force being applied. A force in the line of motion such as a rocket motor or friction will cause an acceleration. A force such as gravity pulling on a satellite more or less perpendicular to the line of motion causes a change in direction. Without that force, the object would continue in a straight line. Balance all the forces and you have no acceleration, or constant speed in a constant direction.

Yes,a change in direction affects acceleration because acceleration is the rate of change of velocity.Velocity is a vector quantity which involes the speed and direction.

Acceleration is a vector. So if the velocity remains constant but changes direction you will still have a non-zero acceleration.

If we are speaking approximately potential acceleration, then no, the substitute wont have effects on something approximately to ensue till it happens to be against something with friction (into the wind, ect.) this would not prepare in empty area, in spite of the undeniable fact that, till one needs to evaluate the myriad of, albeit quite faint, gravitational pulls surrounding them. in spite of the undeniable fact that no rely if it extremely is kinetic acceleration, then particular; the momentum of the object, which nevertheless needs the object to maintain shifting interior the comparable course, might reason the object to decelerate if an on the spot substitute in trajectory have been to ensue. this might, of course, impression acceleration besides; the object, a minimum of collectively as changing course, might lose a great deal of acceleration, and till the "merchandise" consists of organic potential, then it would desire to construct up the acceleration as quickly as back. next time do your homework.
