On earth, the vertical acceleration of any object that's free to move vertically,
and has no artificial force imposed on it, is 9.8 meters (32.2 feet) per second2,
directed downward. The source of the acceleration is the mutual gravitational
attraction between the object and the earth.
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
Positive if the acceleration is also upwards directed, and if you are considering a one dimensional space where you thus only have upwards and downwards as directions. Otherwise you need to more information before you able to answer this question.
When an object is moving upwards, its velocity is directed upwards. If the object is near the Earth or any other planet, then its acceleration is directed downwards, which also means that its upward velocity is decreasing.
The magnitude of the upward acceleration of the load of bricks is the measure of how fast the load is moving upwards.
Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.

An object which is not moving is not experiencing any acceleration, other than the acceleration due to gravity, which, along with mass gives it its weight. The upward force (normal force) acting on the object is equal to but opposite to its weight, and all of the forces acting on the objects are in equilibrium so the net force is zero Newtons.

Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.
If a moving object is speeding up, the acceleration is in the same direction as the object's motion.
The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.
An object moving at a constant speed is not undergoing acceleration because acceleration is a change in velocity over time. Since the object's speed is not changing, there is no acceleration.
No, the acceleration at the highest point is never 0.
Tangential acceleration is the change in speed of an object moving in a circular path, while centripetal acceleration is the acceleration that keeps an object moving in a circular path. Tangential acceleration affects the speed of the object, while centripetal acceleration affects the direction of the object's motion.
The acceleration of an object turning a corner is directed towards the center of the circle that the object is moving along. This acceleration is called centripetal acceleration and is responsible for changing the direction of the object's velocity, keeping it moving in a curved path.
