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.
Without air resistance all objects regardless of their size and mass experience the same acceleration of gravity?
True
How long does thermal energy transfer between objects?
Since different objects have different heat conductivity and different temperatures and heat capacities, the time can vary without limit.
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.
Do heavier objects fall faster or slower than light one?
Without air resistance, heavier and lighter object fall at the same speed. More precisely, they accelerate at the same speed - near Earth's surface that would be 9.8 meters/second2. If air resistance is significant, heavier objects tend to have less air resistance, compared to their weight, so they will usually fall faster.
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 when identical objects are dropped on planets with different gravitational conditions?
Without the interference of air or any other force, they should fall at the same speed. All objects accelerate at the same rate regarding their masses. To conclude, If this was made in a vacuum they should fall at the same speed but in different conditions it may have different results due to air resistance.
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.

True
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.

A marble a textbook and a flaming stick are simultaneously dropped from a height of 10 feet Supposing air resistance upon the falling objects is small enough that it can be neglected which will hit?
Without air resistance? All three will hit the ground at the same time.
Without air resistance all objects regardless of their size and mass exp erience the same acceleration of gravity is it true or false?
It's true, it's true! Galileo proved it.
