Does a penny and a bowling ball fall at the same rate?
Spoiler: the answer is that they will all fall at the exact same rate. Though some objects, like feathers, seem to fall slower because of air resistance.
Where are NASA space shuttles now?

Why do 2 objects fall at the same time?
Consequently, the acceleration is a=Fm=GMR2, which is independent of the mass of the object. Hence any two objects that are subject only to the force of gravity will fall with the same acceleration and hence they will hit the ground at the same time.
Who dropped a feather and a hammer on the moon?
Commander David Scott
Does Dark Side of Moon get sunlight?
The ‘dark side’ of the Moon refers to the hemisphere of the Moon that is facing away from the Earth. In reality it is no darker than any other part of the Moon’s surface as sunlight does in fact fall equally on all sides of the Moon.
Does the sun only shine on one side of the moon?
We know that the Moon is round like a ball, and we know that the Sun may shine on all sides of the Moon. So the only part of the Moon that is truly dark, is the side that’s aimed away from the Sun at any given time. At the time of the full moon, the Sun is shining full on the face we always see.
Do objects fall slower on the moon?
The Moon’s surface gravity is about 1/6th as powerful or about 1.6 meters per second per second. The Moon’s surface gravity is weaker because it is far less massive than Earth. You will notice that the objects fall slowly, because their acceleration toward the surface is only 1/6th what it would be on Earth.
Where are all the space shuttles today?
Retired Space Shuttle Locations
- Shuttle Atlantis – Kennedy Space Center Visitor Complex.
- Shuttle Discovery – Steven F. Udvar-Hazy Center.
- Shuttle Endeavour – California Science Center.
- Shuttle Enterprise – Intrepid Sea, Air & Space Museum.
What is gravity like on the moon?
1.62 m/s²
What happens when you drop a hammer and a feather on the moon?
This air causes friction with objects as they fall through it, called air resistance, which can slow them down as they fall. Because the Apollo crew were essentially in a vacuum, there was no air resistance and the feather fell at the same rate as the hammer.
Do you run faster on the moon?
Thankfully, a group of NASA scientists have finally looked into the question. And, according to the study they published today in the Journal of Experimental Biology, humans can run a lot faster in lunar gravity than anyone ever expected.
Why don’t we use space shuttles anymore?
The shuttle was revealed to be a high-risk, experimental vehicle — something most astronauts had known all along. The subsequent investigation also revealed serious problems with NASA’s safety culture. Still, the space agency took its lashings and made the changes required to get the shuttle flying again.
Did the families of the Challenger crew sue NASA?
Only the Jarvis and McAuliffe relatives had a right to sue the government; all the astronauts’ families could sue Morton Thiokol. McNair, a NASA employee, the father of Jarvis and the mother of mission specialist Judith A. Resnik to file separate suits against Morton Thiokol only.
What will fall first watermelon or egg?
The watermelon also has a lower acceleration because it is heavier and the egg the opposite. So since the watermelon has a greater gravitational force AND lower acceleration – the two effects cancel each other out perfectly, allowing it to hit the ground the same time as the egg.
Will a penny and a feather fall at the same rate?
But because of the coin’s greater mass, it’s also much harder to accelerate the coin than the feather—50 times harder, in fact! The two effects exactly cancel out, and the two objects therefore fall with the same acceleration.
Which will hit the ground first?
In other words, if two objects are the same size but one is heavier, the heavier one has greater density than the lighter object. Therefore, when both objects are dropped from the same height and at the same time, the heavier object should hit the ground before the lighter one.
How many countries have walked on the moon?
three nations
Is the flag still on the moon?
Since the nylon flag was purchased from a government catalog, it was not designed to handle the harsh conditions of space. A review of photographs taken by the Lunar Reconnaissance Orbiter (LRO) indicates that flags placed during the Apollo 12, Apollo 16, and Apollo 17 missions were still standing as of 2012.
How many space shuttles are left?
6 Space Shuttles were built (although only 5 of them spaceworthy): Challenger, Enterprise, Columbia, Discovery, Atlantis & Endeavour. 4 of them are still around, in various museums. Disintegrated after launch, killing all seven astronauts on board.
Does the moon have air resistance?
On the moon, the atmosphere is so thin that it has effective zero air resistance. This is why on the moon the two objects hit the ground at the same time.
Did China land on the moon in 2020?
China’s Chang’e 5 mission, tasked with bringing a sample of lunar dirt back to Earth, successfully landed on the Moon on Tuesday, marking the third time that China has placed a robotic spacecraft on the lunar surface.
Did China make it to the moon?
Chang’e 3, which includes a lander and rover, was launched on 1 December 2013 and successfully soft-landed on the Moon on 14 December 2013….Chinese Lunar Exploration Program.

Do we know what the dark side of the moon looks like?
During a New Moon, therefore, when the hemisphere of the moon which faces us is dark, the entire far side of the Moon is illuminated by the Sun. The far side instead is almost entirely craters; craters piled within other craters, jumbled on top of each other in a chaotic, rough terrain.
Why did we stop going to the moon?
But in 1970 future Apollo missions were cancelled. Apollo 17 became the last manned mission to the Moon, for an indefinite amount of time. The main reason for this was money. The cost of getting to the Moon was, ironically, astronomical.
Which falls faster bowling ball or feather?
The feather-bowling ball duo doesn’t fall at a slower rate because the feather is lighter than just the bowling ball alone — instead, they both fall at exactly the same rate.
Why does the earth pull harder on us than anything else?
Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.
Who owns the moon?
The Outer Space Treaty means therefore that – no matter whose national flags are planted on the lunar surface – no nation can ‘own’ the Moon. As of 2019, 109 nations are bound by the Treaty, and another 23 have signed the agreement but have yet to be officially recognised.
Which ball falls faster?
Heaver objects fall faster. If you drop a heavy and light object together, the heavy one will get to the ground first. This is trick question. I remember in physics that everything falls the same.
Will 2 objects fall same speed?
They think that gravity acts more on a heavier object thus pulling it down faster. In fact, gravity works independently of mass. This means that all objects should fall at the same rate. If there is no air resistance, or the same amount of air resistance, then objects of the same mass will fall at the same rate.
Which would hit the ground first in a vacuum?
Heavier Objects Don’t Hit the Ground First Here is the short answer. If there is no air resistance, after you let go of an object the only force on it is the gravitational force. The gravitational force is proportional to the mass of the object. More massive objects have a greater gravitational force.
