Who dropped the feather and hammer on moon?
Commander David ScottThe Apollo 15 Hammer-Feather Drop At the end of the last Apollo 15 moon walk, Commander David Scott (pictured above) performed a live demonstration for the television cameras.
He held out a geologic hammer and a feather and dropped them at the same time..
Which would hit the ground first in a vacuum?
Answer and Explanation: In reality, the two objects would hit the ground simultaneously if they were dropped from the same height into the void.
Do objects fall at the same rate on the moon?
In the absence of any (significant) resistance to free-fall on the Moon, any two objects should fall at the same rate regardless of mass. However, when there are resistances to free-fall, like air resistance, the weight of the object (mass*force due to gravity) does influence the rate of free-fall.
Will the hammer or the feather reach the ground first?
They reach terminal velocity at the same time and they hit the surface with the same acceleration. If however, they are being dropped on, say Earth, the hammer reaches the ground first because of drag. This is because the feather reaches it’s terminal velocity quicker, because its air resistance increases as it falls.
What will fall first watermelon or egg?
Since the egg is lighter, the gravitational force is less. … 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.
Is there air on the moon?
On the moon, there’s no air to breathe, no breezes to make the flags planted there by the Apollo astronauts flutter. However, there is a very, very thin layer of gases on the lunar surface that can almost be called an atmosphere. … In the moon’s atmosphere, there are only 100 molecules per cubic centimeter.
Do a feather and a rock fall at the same rate?
If no air resistance is present, the rate of descent depends only on how far the object has fallen, no matter how heavy the object is. This means that two objects will reach the ground at the same time if they are dropped simultaneously from the same height. … In air, a feather and a ball do not fall at the same rate.
Do things fall slower on moon?
Since the moon has a smaller mass than the Earth, the gravitational acceleration on the moon is lower, and hence objects will fall “slower.”
Why is there no air resistance on the moon?
On Earth there is a thick atmosphere; therefore, there is a large air resistance to a falling object. On the moon, the atmosphere is so thin that it has effective zero air resistance.
Does the moon have gravity?
What would happen if you dropped a hammer and feather on the moon?
In one hand, he took a 1.32kg aluminium geological hammer. In his other, a 30g falcon feather, 44 times lighter than the hammer. Sure enough, when he dropped them both from the same height at the same time, they hit the ground simultaneously — thus demonstrating Galileo’s theory.
Does a heavier object 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.
Is the moon a vacuum?
The atmosphere of the Moon is a very scant presence of gases surrounding the Moon. For most practical purposes, the Moon is considered to be surrounded by vacuum.
What happens when you drop something in space?
A spatula that got untethered from the astronaut that it was on only to go whizzing off into orbit at 17,500 miles per hour. … Every orbital launch results in debris from rocket parts. Sometimes these parts will stay in orbit, sometimes they’ll burn up, sometimes they fall into the ocean.
Is value of G actually constant?
The force of attraction between any two unit masses separated by a unit distance is called universal gravitational constant denoted by G measured in Nm2/kg2. It is an empirical physical constant used in gravitational physics. … The value of the gravitational constant is the same throughout the universe.
Who dropped balls off the Leaning Tower of Pisa?
Galileo Galilei: Four hundred years ago–or so the story goes–Galileo Galilei started dropping things off the Leaning Tower of Pisa: Cannon balls, musket balls, gold, silver and wood. He might have expected the heavier objects to fall faster. Not so.
Why does a hammer and a feather fall?
Newton’s law of gravity shows that gravity can actually be thought of as an acceleration that is the same for all objects regardless of their mass. So the Hammer and feather in the absence of an atmosphere to cause air resistance fall with the same acceleration.
Do heavier objects fall faster?
Answer 3: In real life, heavier objects sometimes fall faster than light objects, but not because of gravity. Gravity makes all objects increase their speed at the same rate, regardless of how big they are. But if you drop 2 things outside, the air molecules may slow down one thing more than another.
