What is the direction of acceleration due to gravity in upward motion and downward motion?

The direction of acceleration is always in the same direction as the force.
That's nominally toward the center of the Earth.
(Technically, it could be slightly off-center, if you happen to be in the presence
of a large, massive, non-symmetrical piece of the Earth, like a mountain. But
it's pretty accurate to simply say that it's always toward the center of the Earth.)

What type of motion is exhibited by a ball thrown up uniform or non uniform motion why?
If by motion you mean velocity it is non uniform, because the velocity is changing due the acceleration of gravity slowing it down to zero. Then at the maximum height motion is reversed and it accelerates downward back to its original speed but in the opposite direction.
Can an object be moving if acceleration is zero?
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.
For an object to be in projectile motion and what force must be acting on it?
Gravity must be the only force acting on the object, to produce downwards vertical acceleration. There is no force acting in the horizontal direction because there is no acceleration.
When force is perpendicular to the direction of motion is work done?
No. At least not by the force that's perpendicular to the motion. When you push a baby stroller (or a car), you do work, but the force of gravity, downward and perpendicular to the motion, doesn't.
After the diver jumps forward from the diving board the force of gravity will accelerate the diver parallel to the direction of motion?
No. It will accelerate the diver downward only.
What is the difference between infiltration and seepage?
infiltration is strictly downward motion in the direction of gravity while seepage can be in any direction.
Gravity affects this type of motion?
downward motion

What is downward motion?
Downward motion is defined as the movement of one's center of gravity towards the performance surface.
How does gravity affect two componets of projectile motion?
Divide the motion into a horizontal and a vertical component. The horizontal component won't be affected by gravity. The vertical component will get a downward acceleration of 9.8 meters per second per second.
Can an object be moving if acceleration is zero?
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.
Why does the acceleration of an object rolled down an incline increase as the angle of incline increases?
The contribution of the acceleration of gravity in the direction of motion increases as the angle of the incline increases. Or in other words, as the angle between the direction of motion and the force of gravity goes to zero, the acceleration of the object goes to the gravitational acceleration. a = g cos(theta) Where theta is the angle between the direction of motion and verticle, which is in fact (theta = 90 - angle of the incline)Where a is the acceleration of the object down the incline plane and g is the acceleration due to gravity. Theta is the angle between the direction of motion of the accelerating object and the acceleration of gravity. Initially, the angle between a and g is 90 degrees (no incline) and therefore g contributes nothing to the objects acceleration. a = g cos(90) = 0 As the angle of the inclined is increased, the angle between a and g approaches zero, at which point a = g. With no other forces acting upon the object, g is its maximum acceleration.

What kind of motion does the speed and direction not change?
Acceleration in motion refers to a change in speed or direction of that object's motion. So a type of motion in which speed and direction do not change is a motion in which the acceleration is constant (i.e. unchanging).
True or false acceleration is a change in motion?
'Acceleration' is a change in the speed and/or direction of motion.
