Why do you ask. Do you think they should not hit the ground at the same time.
Do you think perhaps a heavier object should fall faster. Let's check it out.
Take a 10-pound stone and a 2-pound stone. We're pretty sure that the 10-pounder
is going to fall faster than the 2-pounder does, but let's try it out anyway.
Take both of your stones to the top of the leaning tower, but don't drop them yet.
Before you drop anything, tie your stones to the ends of a 6-foot string, then
drop them together.
The 10-pounder wants to fall faster, so it hurries the 2-pounder ahead a little.
The 2-pounder wants to fall slower, so it holds the 10-pounder back a little.
Together they fall a little faster than the 2-pounder wants to, but a little slower
than the 10-pounder wants to. Right ?
So when they fall together, they fall slower than a single 12-pound stone would fall.
Some people would be perfectly OK with that.
We've known for roughly the past 500 years that every object on earth falls
with the same speed and acceleration and hits the ground at the same time,
unless air holds it back. If you pump the air out of a tall tube and then drop
things inside the tube, a Bowling ball and a feather drop together and hit
bottom at the same time.
If a penny and a text book were dropped in a vacuum then they will both hit the ground at the same time. This refers to Newton's laws. If they are dropped at the same time on earth then the text book would hit the ground first.
A) the dropped one hits the ground first B) the tossed one hits harder
The ball dropped from the higher height will have a greater force before it hits the ground. This is due to the air resistance that is acting against the ball, and there would be more resistance against the ball dropped at a higher height than a lower height.
If there is no air, the same exact time. But because its on earth, the less dense and less aerodynamic one will land slightly after. Acceleration is about -9.8 meters per second every second
They wouldn't land at the same time. the rock will land first and quickly because a rock have bigger mass than a feather. A feather is very light, if you ever tried to drop it from some height you could see that it takes very long time to land and it might go away to another place too.
Assuming that each object is held with its center of gravity at the same height, and that each is dropped cleanly, with no rotation induced, the one whose lowest part is closest to the ground when dropped will hit first.
Assuming both were dropped from the same height above ground, in a vacuum both would hit the ground at the same time. In a significant atmosphere (e.g. average ground-level on Earch) the bowling ball would hit the ground first.
Both weights will hit the ground at the same time, as gravity accelerates all objects at the same rate regardless of their mass. This is known as the principle of equivalence.
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.
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.
If dropped from the same height, they will hit the ground at the same time.
both reaches the ground at the same time because in the moon there occurs free fall.
Both the cotton and the stone will hit the ground at the same time when dropped from the same height in a vacuum, as they will be subject to the same gravitational acceleration. However, in real-world conditions, the stone will likely hit the ground first due to its higher density and lower air resistance compared to the cotton.
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 both objects have similar air resistance factors, they will both hit the ground together.
Discounting any friction with the air, they would both hit the ground at the same time.
A bullet fired parallel to the gound, over flat ground, and a bullet dropped at the same time from same height will hit the ground at a time so close to each other as to be the same.
