## What happened to the feather and hammer when dropped?

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.

What was the purpose of the 1971 feather and hammer drop experiment performed by astronaut David Scott?

Apollo 15 Video Courtesy of NASA: The 1971 Feather and Hammer Drop Experiment performed by Astronaut David Scott. We analyze the experiment to determine the height from which the feather and hammer were dropped. It is a great, basic, introductory free-fall problem.

Who dropped the feather and hammer?

Commander David Scott
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.

### Who did the hammer and feather experiment on the moon?

astronaut David Scott
In a 1971 live broadcast on television, astronaut David Scott conducted Galileo’s famous hammer and feather drop experiment on the moon surface during the last Apollo 15 moonwalk.

Why does a feather and hammer hit the ground at the same time?

The force of gravity determines how long an object will take to fall to the ground. However, when the experiment was done on the Moon, the feather and the hammer both hit the ground at the same time because, in the absence of air resistance, all objects do in fact accelerate towards the ground at the same rate.

Does a feather fall faster than a brick?

You may wonder, then, why feathers float gently in the breeze instead of falling to the ground quickly, like a brick does. Well, it’s because the air offers much greater resistance to the falling motion of the feather than it does to the brick.

#### What will happen when a hammer and a feather are dropped at the same time and height air resistance is negligible?

A hammer and a feather will fall with the same constant acceleration if air resistance is considered negligible. This is a general characteristic of gravity not unique to Earth, as astronaut David R. The acceleration of free-falling objects is therefore called the acceleration due to gravity.

Would a feather and a hammer hit the ground at the same time?

If a feather and hammer were the two objects he used, then obviously the hammer would hit the ground first. Gravity’s force on objects is the same. Therefore, if you drop 2 things (a hanger and a penny) they will hit the ground at the same time.

Will a feather and hammer hit the ground at the same time?

## Would a brick or feather fall faster on moon?

Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and brick dropped together. Air resistance causes the feather to fall more slowly.

Why does feather fall slow?

Well, it’s because the air offers much greater resistance to the falling motion of the feather than it does to the brick. The air is actually an upward force of friction, acting against gravity and slowing down the rate at which the feather falls. Air resistance causes the feather to fall more slowly.

Why do 2 objects fall at the same time?

Because that object feels a force, it accelerates, which means its velocity gets bigger and bigger as it falls. Because Earth gives everything the exact same acceleration, objects with different masses will still hit the ground at the same time if they are dropped from the same height.

### Why did Apollo 15 drop a hammer and a feather?

The Apollo 15 Hammer-Feather Drop. He held out a geologic hammer and a feather and dropped them at the same time. Because they were essentially in a vacuum, there was no air resistance and the feather fell at the same rate as the hammer, as Galileo had concluded hundreds of years before – all objects released together fall at…

When was the hammer and feather drop mission?

October 2, 2009 In 1971, astronaut David Scott conducted Galileo’s famous hammer/feather drop experiment on the moon, during the Apollo 15 mission.

Who was the first person to drop a hammer on the Moon?

In 1971, astronaut David Scott conducted Galileo’s famous hammer/feather drop experiment on the moon, during the Apollo 15 mission.

#### Why did Galileo drop a feather and a hammer?

He held out a geologic hammer and a feather and dropped them at the same time. Because they were essentially in a vacuum, there was no air resistance and the feather fell at the same rate as the hammer, as Galileo had concluded hundreds of years before – all objects released together fall at the same rate regardless of mass.

What happened to the feather and hammer when dropped? 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…
