The astronauts had to jump as if they carried another person on their backs. Quoting: Anonymous Coward 960185Moon's gravity is that of 1/6 of Earth, therefore the jumps on the moon should have been 6 times higher. With the weight of the spacesuits, the jump should have been 3 times higher than Earth. I think that in the video, the astronaut jumps at almost the same height as an average man would jump on Earth, i.e. about 30 centimeters, which is at odds with the Moon's gravity and the weight of the spacesuit and astronaut. If regular people on Earth can jump 30-40 centimeters, then astronauts on the moon should be able to jump 3 times as much, i.e. 1.20 meters, taking into account the weight of the spacesuit. Look at how much the astronaut bent his leg. Try bending your leg to match and jump; see how high you go. It isn't going to be 30-40 centimeters. |

Physics tells us that the velocity just after the jump would be the same as the velocity just before he lands. The time going up is the same as the time coming down. It is conservation of energy and assuming negligible air resistance. |

Remember Newton's second law, a body at rest remains at rest and a body in motion remains in motion unless acted upon by an external, unbalanced, force. The air provides the frictional force to flag waving and that is why they stop. On Moon the only friction was where the flag attached to the pole and it took a while for that to damp out. |

No. In the absence of friction (a fair assumption on earth, an even better one on the moon) the astronaut will come down at the same speed he goes up. The astronaut did not jump with much force for whatever reason. Maybe he was afraid of going off balance because of his heavy backpack or the unfamiliar environment. The thing to do is to see how long it took him to jump that high. h = (1/2) g t^2 so t = sqrt (2 h / g) That's the time from ground to top, or top back down to ground. Double it for the total jump time. Note that t goes as sqrt(1/g). Moon gravity is 1/6 of earth's, so the jump time on the moon should be sqrt(6) times as long, or about 2.5 times as long, for a given height. And that's about what we observe.

Two questions: Why do the astronauts seem to jump slower, and, why do they fall slower. 1. During the jump we've all seen, the astronaut is carrying far more equipment than any of us do when on earth. He has close to twice his mass (notice I did not say he weighed twice as much). To accelerate something requires a force. In this case the force comes from his legs, and for the sake of argument let's assume he can generate the same force on the moon as he can on the earth, since only a few days have passed since he was on the earth. So, the force is constant, but, the astronaut has about twice the mass. So, F = ma, or a = F/m, therefore the extra mass has limited the acceleration to about 1/2 the acceleration he can generate on the earth. Since he accelerates over the same distance (bent legs to straightened legs), his initial vertical velocity will be less. The statement in the original message that says he would be jumping at a lot faster speed would only be true if he somehow reduced his mass on the moon. Once he leaves the ground, with this slower velocity, the force of gravity of the moon will attempt to bring him back down. But that force is about 1/6th that of the earth. So the speed at which he stops moving up and starts moving down will me slower. Hence, the 'slow motion' effect. The main point is that it is mass that counts for acceleration, not weight. This explains the slower jump speed. However, even with a slower jump velocity, he can typically get a little higher elevation because of the reduced gravity. RDM |

Quoting: Anonymous Coward 882391 Which falls faster? Then why should it fall slower on the Moon? Gravity is gravity. I see this thought experiment all the time and the premise is incorrect. Planets have many billions of times more mass than either a 33 or a 250 pound weight, and for all practical purposes they fall at the same rate. For the purposes of normal problems that will come up, objects no matter the mass fall at the same rate of acceleration on a given planet. But not exactly! The 250 pound weight actually DOES fall slightly faster than a 33 pound weight, because the force of gravity is actually a compounded force of gravity between two masses. In other words although it is an extremely small force, a 33 pound mass has a gravity field as does a 250 pound mass, all mass produces gravity, and this gravity acts on the larger mass. The force is so small as to be immeasurable for all intents and purposes. To understand what I am trying to say, imagine two planets accelerating towards each other as a result of gravitational attraction. It is easy to see in this example that the gravity of both planets is involved in this acceleration. It is no different with smaller masses, it's just that the force is so small that it's not normally necessary to consider. the acceleration due to gravity on a planet IS NOT actually a constant value, and if you've got a mass that is fairly large in proportion to the planet (like for instance a 1.0 X 10^9 kg asteroid would be accelerated measurably faster than a 1.0 x 10^5 kg asteroid by Earth gravity. |
