As we know from the Newton's 2nd Law,
F=ma,F=force,m=mass of the body a= acceleration of the body
a=F/m
When F>0 i.e. even a little amount of force is exerted on the body and it is moving even with a little velocity,acceleration cannot be zero because mass is always >0
No, a body cannot have acceleration when it is momentarily at rest. Acceleration is the rate of change of velocity over time, so if the body is at rest, its velocity is zero, and therefore its acceleration is zero as well.
When a body is rotating in a circular path around an axis.
No, a body cannot have acceleration while at rest. Acceleration is the rate of change of an object's velocity, meaning it requires the object to be in motion. When an object is at rest, its velocity is zero, so there is no change in velocity, hence no acceleration.
When a body has constant velocity, the acceleration is zero. This is because acceleration is the rate at which velocity changes, so if velocity is constant, there is no change and hence no acceleration.
Yes, a body can be in motion but have zero acceleration if it is moving at a constant speed in a straight line. Acceleration measures the rate of change of velocity, so if velocity is constant, acceleration is zero even though the body is in motion.

The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
When a body has constant velocity, the acceleration is zero. This is because acceleration is the rate at which velocity changes, so if velocity is constant, there is no change and hence no acceleration.
zero
Zero.
In classical physics, if a force (e.g. the sum of all forces) acts on a body, the body cannot have zero acceleration (unless the body has infinite mass), since a = F/m. The velocity on the other hand may be zero, since a(t) = v'(t).
Acceleration becomes zero.
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
