If you define the positive direction as pointing down, then the falling object has positive acceleration.
Its magnitude is 9.8 m/s2.
Yes, it is possible to have positive acceleration if an object is speeding up in the direction of motion. Positive acceleration occurs when the velocity of an object is increasing, resulting in a change in speed or direction.
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
For example, you can time how long it takes for an object to reach the floor. You also need to measure how far it falls down. If you assume constant acceleration, there is only one possible acceleration for any possible set of measurements.
Acceleration of an object is positive when its velocity is increasing over time. This means the object is speeding up in the direction of its motion.
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)
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, a falling apple meets that condition.

Either of these is referred to as positive acceleration: A) the object's velocity is increasing in the frame of reference B) the object is being moved in a positive direction in a coordinate plane
Acceleration of an object is positive when its velocity is increasing over time. This means the object is speeding up in the direction of its motion.
Newton's Second Law of Acceleration says it is gravity.
