Yes, but only for a single instant in time.
When you throw a Golf ball or a rock straight up, it has the constant downward acceleration
of gravity from the moment it leaves your hand, but its velocity is certainly not constant.
The velocity steadily decreases until the peak of the toss, and then it switches from
upward to downward velocity. At the very peak, the velocity is zero for an instant.
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
Sure. Anything that's slowing down has velocity and acceleration in opposite directions. -- A ball tossed up in the air has upward velocity and downward acceleration. -- A car stopping for a red light has forward velocity and backward 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, it is possible for a body to have zero velocity but still have acceleration. This occurs when the body is changing its direction of motion, even though its speed remains constant. The acceleration in this case is due to the change in direction, not speed.

The velocity and acceleration can have the same numeric value, but the units will be different. ----------------------------------------------------------------------------------------- No it is not possible. Because so long there is acceleration then the velocity has to change either in magnitude or in direction or in both. So it is not at all possible for acceleration and velocity to be the same simultaneously.
No because velocity defined as speed in a given direction so if speed is 0 then velocity must also be 0
No, because acceleration is the rate of change of velocity.

Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.
Yes, it is possible for a body's velocity and acceleration to be in opposite directions. This would result in the body's velocity decreasing over time while its acceleration remains negative. On a velocity-time graph, this situation would be represented by a curve that starts with a positive velocity and decreases over time.

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
