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 solid lead sphere of radius 10 m (about 66 feet across!) has a mass of about 57 million kg. If two of these spheres are floating right next to each other (centers 20 m apart) in deep space, the gravitational attraction between the spheres is only 540 N (about 100 pounds). How large would this gravitational force be if the distance between the centers of the two spheres were doubled?
You drill a hole right through the center of a spherical planet of radius R and mass M, and drop an
object into it. How long does the object take to reach the opposite surface. Express your answer
only in terms of M, R and the universal gravitational constant G.

According to Newton, what is the force causing that acceleration?arrow_forwardIt was stated that a satellite with negative total energy is in a bound orbit, whereas one with zero or positive total energy is in an unbounded orbit. Why zero or positive total energy is in an unbounded orbit. Why is this true? What choice for gravitational potential energy was made such that this is true?arrow_forwardWhen you travel to another part of the solar system (Jupiter, Mars, etc) what changes, your mass or your weight?

- It is possible to experience weightlessness in a spacecraft flying through space in any set of circumstances, since you're always weightless in space, regardless of whether the engines are firing or not only when you're very far from any massive bodies like planets, moons, or stars only when you are drifting and the engines are shut off only when your are in a circular orbit around a planet, moon, or star If you tried to put on a spacesuit without first wearing an oxygen mask for a while, you would be in danger of carbon dioxide poisoning during your spacewalk quickly asphyxiate due to insufficient oxygen in your bloodstream overheat quickly due to insufficient air circulation in the suit experience considerable pain as the nitrogen in your blood forms bubblesarrow_forwardYou may have an image of Sir Isaac Newton sitting under a tree and after being hit on the head by an apple he suddenly "discovered" the Law of Universal Gravitation. In fact, the theory was a result of years’ worth of research, which in turn was based on centuries of accumulated knowledge. He is credited with determining that the following relationship is universal. The gravitational attraction between two objects varies jointly with their masses (m1 and m2) and inversely with the square of the distance (d) between them. By what percent does the force of gravitational attraction change if one mass is increased by 20%, the other mass decreased by 20%, and the separation is reduced by 25%?arrow_forwardA satellite in orbit around the earth is at an altitude of 107 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.arrow_forward
- A 70 kg astronaut is repairing spaceship at a height of 640 km above the surface of earth. His weight at that location is nearly (g = 10 m s-2)arrow_forwardLet’s imagine that you have an idea for an experiment to fly on NASA’s “Vomit Comet.” (What’s special about this plane? It flies in parabolic paths (aka freefall) which result in near weightlessness. This means that you can ignore the effects of gravity when plan your experiment.) You want to mimic the orbital motion of the planets but by using electrostatic force rather than gravitational. And, instead of a planet, you will be orbiting a droplet of water that is 0.5mm in radius and has an deficit of 1.5 x 106 electrons. The droplet is to orbit around a small (1cm radius) sphere. If you want the droplet to move with an orbital radius of 14cm and period of one minute, what should the charge be on the central sphere? BTW The density of water is 997 kg/m3.arrow_forwardm/s.

- Compare the gravitational attraction between objects on earth and interaction of celestial bodies in space. Which gravitational force is almost negligible? Why? Discuss why the study of a gravitational field is important.arrow_forwardIn baseball, after a pitcher has released the ball, it will accelerate downward due to gravity. To compensate for this downward motion, the pitcher stands on a mound that is raised relative to the rest of the field. If you were to play baseball on the Moon, would you still need a mound? If so, how would its height compare to a mound on Earth?arrow_forward
