6. How much would you weigh on Jupiter, where acceleration due to gravity is 2.65g? g is the acceleration due to gravity on Earth. Assume your mass is 42 kg. 相关知识点: 试题来源: 解析 g=9.8 .FromF=ma,wefindthatapersonwithmass42kgwouldweigh(9.8) (2.65) (42) =1091 N on Jupiter....
Like other moons, Earth’s Moon is in freefall around its planet — Earth, so it experiences zero gravity. This also means that the Moon does not weigh much. Its mass, however, is 7.34 x 10²² kg, which is about1.2% of Earth’s mass. ...
How much does a 28 kg object weigh on Moon? An object weighs 180 N on earth. How much will it weigh on the moon? You weigh 585 N on Earth, what is your mass? What do you weigh on the moon? If your mass on earth is 70 kg, what will be yo...
Take the most massive planet in the solar system, Jupiter, which tips the scales at 316 times the mass of the Earth. You might imagine you would weigh 316 times as much there as here. However, because Jupiter's radius balloons to roughly 11 times as large as Earth's, its gravitational...
One Martian year is also much longer than one Earth year. Gravity-wise, Mars might give you a whole new perspective on bathroom scales. A 100-pound (45.35-kilogram) person would weigh a meager 38 pounds (17.2 kilogram) on Mars; the gravity on the Martian surface is 62 percent lower ...
While solar sails have been designed before (NASA's had a solar sail program back in the 1970s), materials available until the last decade or so were much too heavy to design a practical solar sailing vehicle. Besides being lightweight, the material must be highly reflective and able to to...
Chock-full of methane and nitrogen, not much different from liquid nitrogen. It’s a super-low temperature atmosphere.” “So?” “So this is a supply ship for Europa. Nobody in this crew knows a fucking thing about Titan.” The captain said, “We’re already here.” To that, Kang ...
It's because the human body is way too efficient! It just does not take that much energy to maintain the human body at rest; and whenexercising, the human body is amazingly frugal when it comes to turningfoodinto motion. At rest (for example, while sitting and watchingtelevision), the ...
nearly as big as the Earth itself. In reality, though, the Moon is just a little less than one-third of the diameter of the Earth and a mere 1.2% of the Earth's mass. That's not very much, but it's actually pushing the limits of how large a moon can be in relation to its ...
inertia; another is that gravity acts to accelerate masses, but not massless photons, or "packets" of light (it does a tiny bit, but this is only really noticeable in the vicinity of black holes, where relativistic effects are important). The SI (metric) unit is thekilogram (kg). ...
