Describe how the velocity and acceleration of an object change as it fell from tall building?

The magnitude of the velocity will increase. The velocity will be downward - and since it increases, the acceleration will be downward. The acceleration doesn't change (it will remain constant at about 9.8 m/sec2), unless air resistance becomes significant.

What does acceleration describe?
Rate of change in velocity.
Does velocity describe both speed and acceleration?
No. Velocity describes a speed and a direction. Acceleration, on the other hand, is the rate of change of velocity (in symbols: dv/dt); in other words, how fast does the velocity change.
If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Is there an acceleration when an object traveling at constant velocity and why?
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
What is the best way to describe acceleration?
The change in velocity divided by the time. Hope this helps :)

No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
How would you describe the values for acceleration?
positive or negative change of velocity or change of direction of the speed vector
What is the best way to describe acceleration?
The change in velocity divided by the time. Hope this helps :)
What is the change in velocity over time?
acceleration a----->velocity=acceleration x time: v=a x t
Is Velocity any change in motion?
Yes. Acceleration is a change in velocity; velocity is a change in speed and or direction. I am not sure what motion means in a technical sense (velocity?).
Is Acceleration is a rate that can describe how speed or direction is changing?
Acceleration is a change in velocity. Velocity is defined as the speed of an object in a specific direction. It is a vector quantity. Thus acceleration could be a rate of change of speed, velocity or both. In addition, acceration can be negative. In physics terms, there is no such thing as "Deceleration". Any change is considered to be acceleration.
Is Acceleration is the magnitude of average velocity?
No. Acceleration is (change of velocity) divided by (time interval in which it changed). If velocity doesn't change, then there is no acceleration.
When a cars velocity is uniform what it is acceleration?
Acceleration is change of velocity divided by time; so if the velocity doesn't change, acceleration is zero.
Which best describe what occurs when a body acceleration?
Change in velocity per unit time Change in velocity per unit time Change in velocity per unit time change in velocity per unit time.
