9.8 meters per second
The acceleration on a projectile as it comes down is approximately equal to the acceleration due to gravity, which is 9.81 m/s^2 on the surface of Earth. This acceleration acts in the downward direction and causes the projectile to increase in velocity as it falls towards the ground.
The vertical component of a projectile's velocity is irrelevant. It can be up, down, or zero, makes no difference. As long as projectile motion lasts ... gravity is the only force on the object and you're ignoring air resistance ... its acceleration is constant, and is equal to the acceleration of gravity: 9.8 meters per second2 pointing down.
The vertical velocity component of a projectile changes at a constant rate due to the acceleration of gravity. This acceleration causes the projectile to speed up as it moves downward and slow down as it moves upward. The magnitude of the acceleration is constant near the Earth's surface, at approximately 9.8 m/s^2.
When a cricket ball is projected vertically upward, the acceleration acting on the ball is gravitational acceleration directed downward. This causes the ball to slow down until it reaches the highest point of its trajectory, then it accelerates back downward due to gravity.
I'm not sure of any specific name for "vertical motion" other than falling or acceleration and deceleration due to gravity. You will have the force of gravity. You may also have an element of a centripetal force, but for all practical purposes this would be minimal near the surface of the earth.

It has happened. During the American Civil War, a Union rifleman fired his rifle, and the projectile collided with the projectile fired by a Confederate rifleman - in the barrel of the Confederate's rifle. IIRC, that rifle was displayed in the Museum of American History.

the velocity at the start is the same as when it comes back down to the level. At the top velocity is zero and at the bottom the velocity is acceleration x time where time is 1.37/2 = 0.685s. Acceleration is that of gravity or 9.8 m/s/s, so projectile velocity is 9.8 x .685 = 6.7 m/s; in US system that is 22 ft/sec or 15 mph

No, assuming no air resistance, there will be a constant downward acceleration of 9.8 meters per second square (assuming standard gravity). The vertical component of the velocity will be zero at the top of the trajectory.
Since the velocity of an object is composed of its speed and its direction, then an object under the influence of Earth's gravity will always be changing velocity. If it is near the surface, its speed is slowing down if it is moving vertically up, or speeding up if it is moving vertically down. If it is moving horizontally, its speed is slowing because of air friction. But even when it is in a circular orbit and its speed is not changing, the direction in which it is moving is constantly changing. so its velocity is constantly changing. Since we have no information on what the flight is, there is no useful answer.
Yes, the acceleration due to gravity always points vertically downward, regardless of the direction of an object's velocity. This is because gravity is a force that attracts objects towards the center of the Earth.
hill, drop, fall Think of any five different things (car, train, runner, fly, bird) slowing down as they continue traveling forwards. The direction of motion is shown by the velocity vector. The acceleration in each case is in the opposite direction.
Gravity would be pulling down on a projectile object.
