An object falling from a tall building would accelerate at a rate of 9.807 m/s2 until it reached terminal velocity, at which point it would not accelerate until it impacted the ground. Its velocity would increase as it fell until reaching terminal velocity, and then 0 when it hit the ground.

What happens to an object when it undergoes acceleration is it the speed or velocity that increases?
It is the velocity that increases.
If an object is accelerating what equation relates the acceleration of that object the initial velocity and the final velocity and time?
Vf = Vi + at Where Vf = final velocity Vi = initial velocity a = acceleration t = time
Can an object have a northward velocity and southward acceleration?
Yes, think about this; when you through a ball up in the air the velocity will be positive since its going up but the acceleration will be -9.8 since it is going against gravity.
Does an object experiencing a constant velocity have a zero or non-zero value for acceleration?
If an object is sustaining a constant velocity it has 0 acceleration, because acceleration is either increasing or decreasing speed.
Can an object have zero velocity and nonzero acceleration?
Yes. An object moving at constant velocity has zero acceleration. The constant velocity van be any constant including zero velocity. Mathematics acceleration a=dv/dt = 0. Solving this gives v = constant.
What happens to an object when it undergoes acceleration is it the speed or velocity that increases?
It is the velocity that increases.
Acceleration is the rate at which happens?
acceleration is the rate of change of velocity with respect to time.
If an object moves with constant acceleration what happens to the velocity?
The velocity increases at a constant rate.
If the acceleration of an object is in the same direction as the velocity what happens to the velocity of the object?
a = F/m, where a is acceleration, F is net force, and m is mass in kilograms.
What happens to an object's velocity when it accelerates?
"Acceleration" implies that the velocity changes.
When velocity is zero and acceleration is negative what happens to an object's motion?
At that moment, the object isn't moving - but since the velocity is changing, it soon will.
What indicates the acceleration of an object?
Velocity. A change in VELOCITY will always indicate the acceleration of an object.
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.
When the acceleration of an object is zero what is the velocity at the same time?
As long as acceleration is zero, the object's velocity is constant.
What is the rate at which an object velocity changes?
Acceleration
How are velocity and acceleration different?
acceleration is the increase of speed in a moving object. velocity is the speed and direction of a moving object.
What happens to an object in free fall can it has a constant velocity?
No, due to acceleration its velocity goes on increasing. It is given as v = g t
