yes. If the forces acting on the a moving particle are in equilibrium, (e.g. when a spherical object reaches terminal velocity (neglecting increased air resistance as it gets closer to the ground)) then the particle will be moving at a velocity, that is not 0, yet the velocity will remain constant, and the body will not accelerate or decelerate in any direction, and thus the acceleration is 0.
No. A nonzero acceleration means that the velocity is changing, so it can only have a 0 velocity at a single point in time, such as when a ball thrown in the air reaches its peak.
The velocity at each point in the fluid is a vector. If the fluid is compressible, the divergence of the velocity vector is nonzero in general. In a vortex the curl is nonzero.
It depends on the frame of reference (where it is).On Earth a body on a table is still rotating around the centre of the Earth. This implies a change of direction and thus having a velocity around the centre and an acceleration acceleration due to centripetal force that makes a body follow a curved path. Eben without this the body is orbiting the sun with the same impact
A body can have a constant speed yet a nonzero acceleration when it is in a circular motion because though it is having a constant speed but the direction in which it is moving keeps changing at each instance and since acceleration is a vector quantity,it becomes non-zero.
A factor.
No, if an object has zero acceleration, its velocity cannot be changing. If the velocity is nonzero, it must either be increasing or decreasing, which requires acceleration.
Yes, an object can have zero velocity and nonzero acceleration. This occurs when the object is changing its direction but not its speed. For example, in circular motion, the object's velocity is constantly changing direction, leading to a nonzero acceleration even when its speed is constant.
Yes, an object can have a zero velocity but a nonzero acceleration if it is changing its direction. For example, if an object is moving in a circular path at a constant speed, its velocity is zero at every instant, but its acceleration towards the center of the circle is nonzero.
Yes, an object moving at a constant velocity has zero acceleration even though it has a non-zero velocity. For example, a car driving at a steady speed on a straight highway has a constant velocity but zero acceleration.
Yes. As long as the inital and end positions are different, you will have a nonzero average velocity.
No. A nonzero acceleration means that the velocity is changing, so it can only have a 0 velocity at a single point in time, such as when a ball thrown in the air reaches its peak.
its velocity will change by accelerating in the direction of the force

Yes, but only for an instant.
Yes, it is possible for an object to have zero velocity and non-zero acceleration if the object is changing direction without changing speed. This can happen when an object is in circular motion, where its velocity is always tangential to the circle but its acceleration points towards the center.
If an object has zero acceleration, its velocity doesn't have to be zero. Acceleration is a measure of the change in velocity over time. Zero acceleration means there is no change in velocity over time, namely constant velocity. Constant velocity can be any velocity (including zero velocity or "at rest"), so the object's velocity doesn't have to be zero to have zero acceleration.
