velocity, or acceleration

As an object free falls, it's acceleration is determined by the force of gravity. It's velocity is increasing while the acceleration stays constant if there is no air resistance. If there is air resistance, the object will free fall until it reaches it's terminal velocity. This where the downward force of gravity is matched exactly by an upward force of friction so the net force on the object is zero. This means the acceleration is zero and the object stays at a constant velocity

an object will accelerate perpetually as it falls downward if there is no atmosphere to cause atmospheric friction (which is a force that opposes the direction of an objects motion due to molecules in the atmosphere). If there is an atmosphere, then eventually acceleration will slow down as kinematic (the study of forces) equilibrium occurrs, and then you will have just plain old velocity happening.

* accelerating. Typos really need to be corrected, nowadays. They could lead to a hella lot of confusion. The object increases in speed because of the acceleration induced by gravity which is 9.8m/s^2 or 10m/s^2 (rounded off for convenience).

Velocity changes.

both..it will accelerate and velocity will increase until it hits terminal velocity (where additional speed is negated by wind resistance)

Acceleration is 9.8m/s/s and velocity increases.

acceleration is constant and its velocity increases.
