If you can neglect air resistance, then all you need is the time spent falling.
?Initial velocity?
What is the only factor needed to calculate change in velocity due to acceleration of gravity 9.8 ms?
To calculate velocity using acceleration, start by multiplying the acceleration by the change in time. For example, if the acceleration is 10 m/s2 and the change in time is 5 seconds, then there is a 50 m/s increase in velocity. Then, add the initial velocity to the increase in velocity.
If there is no air resistance, gravity will accelerate the falling object, that is, it will change its velocity.
Gravity changes the velocity of an object that is in "free fall" (that is, one that is only subject to the force of gravity). Near Earth's surface, this change of velocity due to gravity occurs at a rate of 9.8 (meters / second) / second; usually this is written as 9.8 meters/second2.

Because acceleration is the rate of change of velocity: it is a measure of how quickly velocity is changing.
To calculate velocity using acceleration, start by multiplying the acceleration by the change in time. For example, if the acceleration is 10 m/s2 and the change in time is 5 seconds, then there is a 50 m/s increase in velocity. Then, add the initial velocity to the increase in velocity.
