Calculating Acceleration on the Surface of Venus - Physics Forums
2022年5月15日 · Friends, hello everyone! Please help with this calculation. The mass of Venus is 81.5% that of the earth, and its radius is 94.9% that of the earth. (a) Compute the acceleration due to gravity on the surface of Venus from these data. (b) If a rock weighs 75.0 N on earth, what would it weigh at...
Attractive force between Venus and Sun - Physics Forums
2012年10月29日 · In summary, the conversation involved finding the attractive force between Venus and the sun using the equation F = Gm1m2/d^2, where G is the gravitational constant, m1 is the mass of the sun, m2 is the mass of Venus, and d is the distance between their centers.
Using Venus in the Parker Solar Probe mission - Physics Forums
2018年4月10日 · The Parker Solar Probe uses Venus' gravity to perform a series of flybys, gradually decreasing its distance from the sun with each pass. This allows the probe to gather data and make observations at different distances from the sun, providing a more comprehensive understanding of the solar environment.
Question Regarding Determining the Mass of Venus - Physics …
2020年9月18日 · Venus is in the news! I looked up this well-regarded paper by A. S. Konopliv, W. B. Banerdt, and W. L. Sjogren Venus Gravity: 180th Degree and Order Model They list values for GM (see attached picture), such as GM 324858.63 ± 0.01 so in principle calculating M should be trivial. The problem is I am orders of magnitude off from the actual value.
Gravity and Weight: How Do They Compare on Different Planets?
2010年7月5日 · In summary, the question is asking how the weight of an object with a mass of 25kg on Earth would compare to its weight on Venus, where the acceleration due to gravity is 8.8m/s^2. The answer depends on the angle of inclination of the inclined plane and the friction between the plane and the object.
Venus Magnetic Field: Dynamo Theory & Slow Rotation - Physics …
2009年10月10日 · The Venus magnetic field is weaker than Earth's because of its slow rotation. Earth's rotation is much faster, causing its core to churn and generate a stronger magnetic field. Additionally, Venus has a smaller and less active core compared to Earth's. How does the Venus magnetic field affect the planet?
Dissociation of H2O due to Photon energy. - Physics Forums
2006年10月4日 · The question requires knowledge of the energy of a photon and the amount needed to dissociate a water molecule from the gravity of Venus. The conversation also considers the possibility of recombination and sets an upper limit for the amount of water Venus could have had when it first formed.
Gravity facts, or close to fact - Physics Forums
2017年7月9日 · The conversation also touched on the question of why Venus does not get sucked into the sun, with the response being that it is covered by Newton's classical theory of gravity. The conversation then shifted to understanding how gravity affects orbits and the need to first understand Newtonian laws of motion.
Is Venus the key to economic success in our solar system?
2020年5月4日 · Venus has among the safest most cushioned existences. A key question is humanities ability to breed in space. Even if pregnancy could happen you still get high doses of radiation. Then questions about early childhood in low or strange gravities. We could build massive space habitats with full gravity and thick shields. Venus also has the meteor ...
