The speed at which an object falls and the acceleration at which it falls are always the same value?
No. In a vacuum, all objects fall with the same constant acceleration, meaning that their speed constantly increases. Near the surface of the earth, the speed of any falling object increases by 32.2 feet (9.8 meters) per second every second. These numbers represent the "acceleration of gravity" at the earth's surface.
How does gravity affects the acceleration of a falling object?
The bigger the object the faster it causes it to fall until it reaches terminal velocity, then it falls at a constant speed.
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.
When an object reaches its termainal speed its acceleration is zero right?
Acceleration is zero when the object's speed and direction stop changing.
Can a body have decreasing acceleration but increasing speed?
Of course. The magnitude (size) of acceleration is the rate at which speed is changing. As long as the magnitude of acceleration is more than zero, speed is increasing. If the magnitude of acceleration is decreasing, then speed is growing more slowly, but it's still increasing. That's exactly what's happening to an object falling through air. As it falls faster and faster, the force of air resistance increases. The object's acceleration shrinks, and it's speed increases more slowly. When the force of air resistance is equal to the object's weight, the net force on it is zero, its acceleration is zero, and its speed stops increasing. It's then at 'terminal velocity'.

What is the appropriate equation for how fast an object freely falls from a position of rest for how far that object falls?
The equation for speed or fast is v=at and the distance is d=1/2 at2 the acceleration is 'a'.

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 is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
When an object reaches its termainal speed its acceleration is zero right?
Acceleration is zero when the object's speed and direction stop changing.
When ever an object is standing still which value is always zero?
Its speed, velocity, and acceleration are all zero.

Is it possible for an object to have an acceleration when the speed of the object is constant?
Yes, if apply at the right angles the acceleration can change the object's current direction without effecting its speed.
Can a object with no acceleration be stationary?
If acceleration means to increase in speed or pace, then a stationary object is static, without movement, without acceleration. But, if an object is moving at a constant rate, then I suggest acceleration is not present, unless, or until the objects speed increases. Yes, an object with no acceleration may be stationary.
Why does the acceleration of an object affect the speed?
Acceleration is simply a measurement of how the speed is changing, over time.
The rate of change in an object's velocity is the object's what?
Acceleration.
