You are explaining to friends why an astronaut feels weightless orbiting in the space shuttle, and they respond that they thought gravity was just a lot weaker up there. Convince them that it isn’t so by calculating how much weaker (as a %) the force (or acceleration) due to gravity is 380km above the Earth’s surface. [

Show that the areal velocity for a circular orbit of radius r about a mass M is At=12GMr . Does your expression give the correct value for Earth’s areal vilocity about the Sun?
Calculate the effective gravitational field vector g at Earths surface at the poles and the equator. Take account of the difference in the equatorial (6378 km) and polar (6357 km) radius as well as the centrifugal force. How well does the result agree with the difference calculated with the result g = 9.780356[1 + 0.0052885 sin 2 0.0000059 sin2(2)]m/s2 where is the latitude?
Following the technique used in Gravitation Near Earth’s Surface, find the value of g as a function of the radius r from the center of a spherical shell planet of constant density with inner and outer radii Rin and Rout . Find g for both eq and for RinrRout . Assuming the inside of the shell is kept airless, describe travel inside the spherical shell planet.
Check Your Understanding Assume you are in a spacecraft in orbit about the Sun at Earth’s orbit, but far away from Earth (so that it can be ignored). How could you redirect your tangential velocity to the radial direction such that you could then pass by Mars’s orbit? What would be required to change just the direction of the velocity?
Check Your Understanding If we send a probe out of the solar system starting form Earth’s surface, do we only have to escape the Sun?

Many people mistakenly believe that the astronauts that orbit Earth are “above gravity.” Calculate g for space shuttle territory, 200 km above Earth’s surface. Earth’s mass is 6.0 × 1024 kg, and its radius is 6.38 × 106 m (6380 km). Your answer is what percentage of 10 m/s2?
You know that the increasing speed due to gravity on the surface of the earth is 9.8 m/sec2, which the length of a incredible circle around the earth is 4 x lo7 m. You're given that the proportions of moon/earth distances across and masses are Dm Mm = 0.27 and = 0.0123 De Me respectively. (a) Compute the least speed required to elude from the moon's gravitational field when beginning from its surface. (b) Compare this speed with warm speeds of oxygen atoms at the moon's temperature which comes to 100°C. 59
Many people mistakenly believe that astronauts that orbit the Earth are "above gravity." Calculate the acceleration due to gravity (g) for space shuttle territory, 200 kilometers above the Earth's surface. Earth's mass is 6 x 1024 kilograms and its radius is 6.38 x 106 meters (6380 kilometers). Your answer is what percentage of 9.8m/s2? (Can you help me break it down in a way that I could understand and calculate?)
A satellite in orbit around the earth is at an altitude of 41.5 percent of the earth's radius. Rounding off our old friend "g" to ten meters per second squared, what is the acceleration due to earth's gravity at the satellite? Your answer should be in meters per second squared, but do not put the unit, just the number.
