both reaches the ground at the same time because in the moon there occurs free fall.
Both the feather and the hammer will hit the ground at the same time when dropped from the same height in a vacuum. This is due to the principle of gravity, which accelerates all objects at the same rate regardless of their mass.
as done in Galileo's experiment when he dropped a large rock and a feather from a tall tower both hit the ground at the same moment when dropped from the same height.
No, a feather and a nail would not reach the ground at the same time if dropped at the same height in a vacuum. This is because the feather experiences more air resistance, slowing its fall compared to the nail which falls faster due to its higher mass.

If dropped from the same height (a few meters), they would appear to hit the ground at the same time, according to the experiments of Galileo. However, this neglects air resistance on the basketball, which will slow it down more and cause it to hit the ground later (very slightly later). The baseball, which has a smaller area and therefore less air resistance, will hit the ground first.
If there was no air resistance and a feather and a penny were dropped from the same height they would both pick up speed by the same amount and they would hit the ground at the same speed and at the same time.
Gravity affects the bounce of a basketball because if there is gravity, the basketball will come back down after it bounces. But if there is no gravity, the basketball will bounce and travel indefinitely upwards and never come back down until a gravitational force pulls the basketball towards it.
10 feet from the ground.
It depends on your height.
When an object is dropped from a certain height, the time it takes to reach the ground is independent of the height (assuming no air resistance). Therefore, whether you drop the object from three times the initial height or the original height, it will still take the same time (T) to reach the ground.
The ball dropped from 4m height has more kinetic energy just before it hits the ground because it has a higher velocity due to falling from a greater height. Kinetic energy is directly proportional to both mass and the square of velocity, so the ball dropped from 4m height will have more kinetic energy than the one dropped from 2m height.
The official height of an NBA basketball hoop is 10 feet from the floor to the rim.
