Acceleration is the change in velocity of an object. If an object is travelling at an unchanging speed, its speed is neither increasing (which would make a positive acceleration) nor decreasing (which would make a negative acceleration). Thus, the acceleration is 0.
That means there is no net force acting on an object.
It's simple arithmetic. [ F = m A ] where F = force, m = mass, A = acceleration.
If 'A' is zero, the right side of the formula is zero, then the left side must also be zero.
The net force being zero may mean that there are no forces acting on an object, but also could mean that there are forces acting on an object, but they are in equilibrium.
Correct. If you released an object into deep space and there is no gravitational forces acting on it, the object would continue to travel at a constant velocity forever.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.
Whenever velocity is constant, the acceleration is zero. This also works when the velocity is zero, the acceleration is zero. That pretty much means the object isn't moving. But, yes/ If velocity is constant, accleration is zero.
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.

The acceleration would be zero because the turtle is moving at a constant speed
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.

Yes. An object moving at constant velocity has zero acceleration. The constant velocity van be any constant including zero velocity. Mathematics acceleration a=dv/dt = 0. Solving this gives v = constant.
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
