Why do different objects in free fall not all fall at the same rate when you test it?
Without air resistance or other forces (other than gravity, that is), falling objects will accelerate at the same rate, and they will take the same time to fall a certain distance. If this is not the case, then the most likely cause is there IS air resistance.
What happens to two objects with the same mass that fall at the same time?
If two objects have the same mass and are dropped from the same height at the same time in a vacuum (without air resistance), they will reach the ground at the same time. This is because all objects accelerate towards the ground at the same rate due to gravity.
Why do some objects fall at a different rate than others?
Objects fall through air at a different rate due to the amount of air resistance. Feathers or dandelion "parachutes" fall at a much slower pace than coins. However there is an experiment called "The coin and the feather". A glass tube about 6cm in diameter has a penny and a penny placed inside before the air is evacuated using a vacuum pump. The tube is then sealed. If the tube is held vertically the coin and feather are both at the bottom. If the tube is then swiftly inverted, so that what was bottom becomes top, the coin and feather are seen to fall at the same rate. Unbelievable unless you actually see it.
How does nature uses air resistance?
Nature uses air resistance to slow down the speed at which objects fall through the air. This resistance helps in the dispersal of seeds from plants, the flight of birds, and the movement of insects. Without air resistance, these natural processes would be altered.
What would the world be without air resistance?

Why don't all objects fall to the earth at the same velocity even though the acceleration?
The acceleration is the same for all objects, as long as air resistance is insignificant. After a while, different objects will have different amount of air resistance. Also, even without air resistance, the speed depends not only on the acceleration, but also on how how long the objects are falling.
What happens if there were no friction?
Without friction, objects would have no resistance, therefor loose no energy as a result. For example, without friction a ball could roll up and down a half-pipe continusily without loosing hight.

Why is there no drag in space?
There is no drag in space because there is no atmosphere to create resistance against an object's movement. In space, objects can move freely without experiencing air resistance, which allows spacecraft to travel at high speeds and for objects to orbit planets without slowing down.

How can you measure rolling resistance?
Roll the object down an inclined plane. Adjust the angle so that the objects rolls down without sliding at a constant speed. When that happens, the tangent of the angle of the plane relative to the horizontal is the coefficient of rolling friction.
Why falling objects don not move forward with a speed of 17700 mph?
And what makes you think an object would fall, or should fall, precisely at such a speed? How do you get that number? - Anyway, that's not the way our Universe works. Without air resistance, an object that falls downward falls faster and faster - its speed increasing by 9.8 meter/second every second. With air resistance, a falling object will eventually reach a speed at which friction (air resistance) balances the downward force of gravity. This speed is different for different objects.

What would happen to falling objects if the is removed so that air resistance disappears?
Without air resistance, falling objects would accelerate at a constant rate due to gravity. This means that they would fall faster and reach the ground in a shorter amount of time compared to falling with air resistance. The absence of air resistance would also remove any upward force opposing the motion of the falling object.
Without air resistance all objects regardless of their size and mass experience the same acceleration of gravity?
Yes, that is correct. In the absence of air resistance, all objects fall at the same rate due to gravity. This is known as the acceleration of gravity and is approximately 9.8 m/s² near the surface of the Earth.
