In the absence of gravity or other forces, objects wouldn't accelerate. There would be no falling. In fact, you'd have a difficult time saying which direction was down.

Those semantics aside, objects near the earth accelerate at a rate of about 9.81 $\frac{m}{s^{2}}$ $m/s^2$ . If an object starts out not moving and is allowed to fall, one second later it will be moving at 9.81 $\frac{m}{s}$ $m/s$ . After two seconds it will be moving 19.62 $\frac{m}{s}$ $m/s$ .

The velocity of a falling object ( $v$ $v$ ) depends on the time it has been falling ( $t$ $t$ ), the acceleration of gravity ( $g$ $g$ ), and the velocity it had at time zero ( $v_{0}$ $v_0$ ).

$v = g \cdot t + v_{0}$ $v = g*t + v_0$
