both reaches the ground at the same time because in the moon there occurs free fall.
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.
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.
They would hit the surface together, after a very long time. Gravity on Ceres is pretty light.
air resistance, on the moon they did an experiment where they dropped a hammer and a feather at the same height and time and they hit the ground at the same time
10 feet
If they are dropped from the same height, they will fall at equal velocities because there is no air resistance and their accelerations by gravity are equal.
10 feet from the ground.
It is air friction. An aeroplane flying into a headwind will use up much more fuel than an aeroplane flying with a tailwind. Air friction means that a feather would take much longer to reach the ground than a lead weight dropped from the same height. Yet, if the feather and the lead weight were to be dropped in a vacuum (not subjected to air resistance) they would both reach the ground at the same time.
It depends on your height.
The official height of an NBA basketball hoop is 10 feet from the floor to the rim.
Did the height of the basketball net from the ground change from 12 feet to 10 feet or from 10 feet to 12 feet Did the height of the basketball net from the ground change from 12 feet to 10 feet or from 10 feet to 12 feet
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.
