If you are ignoring wind and other variables then the upward acceleration is negative velocity caused by gravity. So in most cases (-9.8 m)/(s^2)
It reduces the acceleration of the falling object due to friction.
The acceleration of a falling object is called gravity. A free-falling object has an acceleration of 9.8 m/s/s when going downward on Earth.
Yes it can, and it's really easy. -- A stone tossed upward, before it peaks and starts falling, has upward velocity and downward acceleration. -- A car driving east and slowing for a stop-sign has eastward velocity and westward acceleration.
On Earth, a free-falling object has an acceleration of 9.8 meters per second2.

Gravity
Acceleration. A free-falling object falls at constant force, and thereby at constant acceleration.
No, the acceleration at the highest point is never 0.
Newton's Second Law of Acceleration says it is gravity.
rate of acceleration
The farther away from an object on gets, the less powerful the gravitational pull by that object is. As one moves upward from the surface of the earth, the earth's gravitational pull has less of an effect. Since acceleration due to gravity is negative (-9.8 m/s2), the acceleration due to gravity will increase (the acceleration would decrease if you are considering falling down towards the earth to be positive, not negative velocity). This means that the object will not fall as fast, or that of the object is traveling upwards, it will not slow down as rapidly.
