Is it accelerating? Yes, because the direction of its velocity is changing. If the direction of the velocity vector is changing, the velocity is changing. This means that there must be acceleration

Yes.
Acceleration is a change in velocity with respect to time.
Velocity is a vector and has both a magnitude ("speed") and direction. If either the magnitude of the velocity or its direction changes then the object is accelerating.
Can you think of an instance when an object could be moving at a constant speed, but is changing direction? How about when an object is moving in a circle. An object can be going around a circular path at some uniform speed, but because it is always turning, it is always accelerating. The acceleration the car experiences in this case would be centripetal acceleration (resulting from a centripetal force which is directed radially inward towards the center of rotation).
In this case, the car is accelerating, but its speed remains constant.
centripetal acceleration = v^2 / r
where v is the object's speed and r is the radium of rotation.

Yes. Acceleration is a change in velocity.
Velocity is a vector quantity - speed and direction.
A car that is driving in a circle can mantain a constant speed, but since it's constantly changing direction, it's accelerating.

An acceleration is any substitute in velocity OR ANY substitute IN course. yet a consistent velocity demands that the object is shifting in a right this moment line with consistent velocity so neither of those factors are changing. And on your occasion you're changing your velocity by ability of making use of the accelerator so which you're no longer shifting at the two consistent velocity OR consistent velocity. in case you flow around a nook you will desire to have the comparable velocity yet as you at the instant are shifting in a course then your velocity has altered. to furnish an better occasion. you're vacationing North from Seattle to Vancouver at a gradual a hundred km / hr so which you're coming near vancouver at a hundred km/hr Foolishly you ask a physics student to envision the map and he turns you east in direction of spokane. you're nonetheless vacationing on the comparable velocity yet how quickly are you coming near vancouver. you would be able to additionally be going far flung from it at consistent with danger 10 km/hr given the guidelines I quote. So your velocity RELATIVE TO VANCOUVER has altered and you have had an acceleration.

No. By definition, constant speed = 0 acceleration.

noo acceleration is change of speed over time... if the speed is constant than acceleration is 0
10 months in a physic class that all i have learned lol

yes, it can if it is changing direction. acceleration is a change in speed AND direction

if the car is on the ground...it is going around the earth, therefore accelerating towards the center of the earth with gravity as the centripetal force.

yes!
if it's in circular motion
or just continuously changes its direction while maintain the same speed

Yes. Accelerating just means that the car is not idle.
