In order to answer this, you have to make two assumptions:
#1). We're talking about a falling object on or near the Earth.
#2). We're ignoring the effects of air resistance.
If both of those are true, then the falling object picks up speed as it falls.
At any moment, its speed is 9.8 meters per second (32.2 feet per second)
faster than it was one second earlier.
That number is called the "acceleration of gravity" on Earth. Notice that
the mass or weight of the object doesn't matter.
You asked for the velocity, which means speed and direction. I've explained
the speed, and the direction is always down.

Can an object be accelerating if it has constant velocity?
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
What is velocity used for?
Velocity is the rate of change in an object's location over time, also known as speed.
Is an object's change in position relative to a reference point over a period of time?
In the question, "an object's change in position...over...time" is a perfectly reasonable definition of velocity.
How does motion of an object change over time?
Its velocity is reduced as a result of friction and drag.
How are speed and changes in an object's position related?
Change in position over time is velocity ("speed").
When does a force change the velocity of an object?
If the object is in free-space, and any force applied over a period of time will change the velocity of an object. Force = mass * acceleration. Acceleration = velocity / time. Therefore, Force = mass * velocity/time.
How does velocity work with roller coasters?
Velocity is what makes an object change position over time.
Can an object be accelerating if it has constant velocity?
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
What is velocity used for?
Velocity is the rate of change in an object's location over time, also known as speed.
Is displacement the change in velocity of an object?
Velocity is change in displacement over time.
When does an object undergoes acceleration?
Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.
Is an object's change in position relative to a reference point over a period of time?
In the question, "an object's change in position...over...time" is a perfectly reasonable definition of velocity.
How does motion of an object change over time?
Its velocity is reduced as a result of friction and drag.
What is the formula you use to determine the accelation of an object moving in straight line?
Change in velocity over the change in time
How are speed and changes in an object's position related?
Change in position over time is velocity ("speed").
Acceleration is the rate at which happens?
acceleration is the rate of change of velocity with respect to time.
What is the rate at which an object changes position in one direction?
Velocity is change in position, or displacement, over time.
