If the object is falling close to earth the acceleration would be 9.81m/s^2. Be sure to define direction as positive or negative in the problem! (When I do problems I like to define the down direction as positive so I don't have to deal with too many negatives)
No, but it is possible to not have an increase in speed. Because velocity is a directional quantity, not a scalar one, an object in freefall (by definition within a gravity field) is always under acceleration, just not necessarily one that alters its speed or even its position. Objects in orbit around a planet are in freefall (hence weightlessness) where the tangential component of their forward motion opposes the pull of gravity.
Freefall is when an object falls under the influence of gravity alone, without any other forces acting on it. In a non-freefall scenario, objects may experience other forces such as air resistance or propulsion that affect their motion.
An object is considered weightless when there is no normal force acting on it because weight is the force exerted by gravity on an object's mass. In freefall, the object is only subject to the force of gravity, which causes it to accelerate with the same acceleration as the object itself, resulting in a sensation of weightlessness.
An object is closest to being in freefall right before it hits the ground, when air resistance has slowed it down such that its acceleration is primarily due to gravity. At that point, the object's speed is nearly constant and it is falling solely due to the force of gravity.
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)

In freefall, an object's velocity at a certain time can be calculated using the equation v(t)=a*t Where a=acceleration. On Earth's surface, acceleration due to gravity is equal to 9.8 m/s^2
Acceleration is change in velocity. So it depends on both velocity and time.
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
An object in freefall accelerates at a constant rate due to the force of gravity acting on it. The acceleration due to gravity on Earth is approximately 9.81 m/s^2, causing the object's velocity to increase by this amount every second.
The only force acting on an object in freefall is gravity. This force causes the object to accelerate downward towards the Earth.
To calculate the vertical acceleration of an object, you can use the formula: acceleration change in velocity / time. This means you divide the change in velocity by the time it takes for that change to occur. The resulting value will give you the vertical acceleration of the object.
It depends on the shape of the object and therefore its drag coefficient. For example, you can slow down your freefall by spreading your limbs out.
