It means that the velocity of the body increases constantly at a rate of the given acceleration.
Its acceleration is zero, which is constant
Acceleration must be constant to use kinematic equations. Acceleration need not be constant if working with energy.
It's possible, but not necessary, that a particle moving with constant speedhas zero acceleration. In order for acceleration to be zero, it's also necessarythat 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".
Constant speed means that speed doesn't change. Constant acceleration means that acceleration doesn't change. (If the acceleration is anything but zero, speed WILL change.)
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Its acceleration is zero, which is constant
If your velocity is constant, then your acceleration is zero.
Force = (mass) times (acceleration) Constant force produces constant acceleration.

If the velocity is constant then there is no acceleration. The acceleration is zero.
Unless the train is in a curve, you cannot have constant speed and constant acceleration. You either have constant speed and zero acceleration, or you have changing speed and constant acceleration. Please restate the question.
Constant speed means that speed doesn't change. Constant acceleration means that acceleration doesn't change. (If the acceleration is anything but zero, speed WILL change.)
There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.
Yes - for a while. Or indefinitely, if you will accept zero acceleration as "constant acceleration".
No it cannot. It is either one or the other. For constant velocity, acceleration must be 0, meaning there is no acceleration happening here. If there is constant acceleration, then the velocity is constantly changing.
Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.
