What Is the Moon's Temperature? We would like to show you a description here but the site won't allow us. Now, the radius of the Moon = 1.74 x 106 m. Now, putting all the values of G, we can get: = 6.673 x 10-11 x 7.342 x 1022 /(1.74 x 106 )2, Therefore, value of g(Moon) = \[\frac {1} {6}\] or 16.7% of g(earths surface). The same equation that is used to get the value of g on Earth can be used to calculate the value of g on the surfaces of other planets. The second interesting case concerns living on a spherical shell planet. Both are larger than their equilibrium values showing that the upper layers of the Moon are strong enough to support elastic stress. The acceleration due to gravity is lower on the Moon than on Earth. If the earth and moon are assumed to have the same density, the ratio of radii of moon and earth will be, Acceleration due to gravity on moon is 16 of the acceleration due to gravity on earth. Your object was accelerating because gravity was pulling it down. Compared to the gravitational force that the earth exerts on the moon, the gravitational force the moon exerts on earth: (2 marks). 19. = Understanding the gravitational acceleration Ans. The mass of earth is 10 times that of mars. Moon as well, like other massive objects in the Universe, attracts every other massive body gravitationally. A plumb bob will always point along this deviated direction. What is the mass of an object that experiences a gravitational force of 685 N near Earth's surface where g 9.80 m/s2? r 2 This is only 0.34% of the value of gravity, so it is clearly a small correction. IN (b) How much would he weigh in newtons when he is on Mars, where the acceleration due to gravity is 0.38 times that on Earth? r G is the universal gravitational constant, with a value of. The gravitational potential V at an external point is conventionally expressed as positive in astronomy and geophysics, but negative in physics. The gravitational field of the Moon has been measured by tracking the radio signals emitted by orbiting spacecraft. (2 marks). Because the size of the earth is larger than the moon, the acceleration due to gravity on the earth is larger than that on the moonby about six times, making the acceleration due to gravity on the moon to be about 1.6m/s. Why is more fuel required for a spacecraft to travel from the Earth to the Moon than to return from the Moon to the Earth? C. an object on the moon is six times lighter than on earth. This scenario has been proposed in many science fiction stories. V Which one of the following statements is true about the mass and weight of an astronaut on the Moon's surface, compared to Earth?

All in all, gravity runs the gamut here in the solar system, ranging from 0.38 g on Mercury and Mars to a powerful 2.528 g atop Jupiter's clouds. The acceleration due to gravity on the Moon is one-sixth that on Earth. Language links are at the top of the page across from the title. is the gravitational constant, and
