Yes, satellite orbiting the Earth in a Geo-Stationary Orbit has 0 Velocity relative to a point on the Earth, BUT it experience the 'Pull' (acceleration) of Gravity, which prevents it from escaping its Orbit. The Gravity is LESS than that at the surface of the Earth, but not 0.
The feeling of WEIGHTLESSNESS is not due to Zero Gravity, but due to the fact that Object is FALLING through its Orbit. A Person Falling "feels" Zero Gravity.
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
average acceleration is the average of the acceleration of a body in its entire motion where as instantaneous acceleration is the rate of change of velocity at an instant. it may be a function of time or velocity or displacement.
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 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.
The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.
The acceleration is zero for a body having constant velocity.
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.

Yes, it is possible. For example, if you through an object up, its velocity would initially be in the "up" direction, but its acceleration would be in the "down" direction.
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
