Why did the Apollo 15 astronauts drop a hammer and a feather simultaneously on the moon?
The Apollo 15 Hammer-Feather Drop 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 when astronauts dropped a hammer and a feather at the same time on the moon?
Astronaut David Scott re-created, in 1971 during the Apollo 15 mission, Galileo’s “falling bodies” experiment by dropping a hammer and feather on the moon at the same time. Simply, both fell at the same rate because there was no air resistance.
What objects did Apollo 15 drop on the moon?
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.
What astronaut dropped a feather and a hammer on the moon to see which would hit the surface first?
Galileo
On the Moon: As it happened! Well, in my left hand, I have a feather. In my right hand, a hammer. And I guess one of the reasons that we got here today was because of the gentleman named, Galileo a long time ago, and made a rather significant discovery about falling objects and gravity fields.
Which falls faster feather or rock?
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.
How much does a person weigh on the Moon?
Your weight on the Moon is 16.5% what you would experience on Earth. In other words, if you weighed 100 kg on Earth, you would weigh a mere 16.5 kg on the Moon. For you imperial folks, imagine you tipped the scales at 200 pounds. Your weight on the Moon would only be 33 pounds.
How did the crew of Apollo 15 demonstrate that Galileo was correct in his thinking about falling objects in a gravitational field?
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.

Who dropped a hammer and a feather on the moon?
Commander David Scott
Back in 1971, on his last day on the moon, Apollo 15 Commander David Scott tested this theory. In one hand, he took a 1.32kg aluminium geological hammer. In his other, a 30g falcon feather, 44 times lighter than the hammer.
Would a hammer or feather hit the ground first on the moon?
Based on Scott’s experiment, on the moon, both hammer and feather reached the ground at the same time, proving Galileo’s 400-year-old theory that objects dropped from the same height reach the surface at the same time regardless of their weight.
What happens when hammer and feather drop at the same time and height?
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.
Do lighter objects fall faster?
Acceleration of Falling Objects Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
What was the hammer and feather drop in the Apollo 15?
The 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.
What happened at the end of the last Apollo 15 walk?
Please try again later. 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.
How did Joe Allen describe the Apollo 15 demonstration?
Mission Controller Joe Allen described the demonstration in the “Apollo 15 Preliminary Science Report”: “During the final minutes of the third extravehicular activity, a short demonstration experiment was conducted.
