The gravity on Mars is about 38% that of Earth's gravity. Let's say some cargo has a mass of 15 kg here on Earth. First, what would be the weight of that cargo in kilograms on Mars? Explain your answer. Second, what would be the mass of that cargo in kilograms on Mars? Explain your answer.
The space station is at 400km altitude, and the earth radius is 6378km. Calculate g in the space station. How can you explain that the astronauts are weightless?
1.) In what way(s) is Einstein's general theory of relativity superior to Newton's theory of universal gravitation? For each way, give an example of a case where Einstein's theory provides a more accurate description of physical phenomena than does Newton's. (Select all that apply.) A.) Newton's theory originally held that the orbit of a spherical object about another will be an open curve for which the point of closest approach slowly precesses. Einstein's theory correctly predicts that gravitational forces lead to orbits of closed ellipses. B.) Einstein's theory correctly predicts the deflection of light passing near a massive object, while Newton's theory predicts a deflection that is one-half the observed deflection. C.) Einstein's theory correctly predicts that the orbit of a spherical object about another will be an open curve for which the point of closest approach slowly precesses. Newton's theory originally held that gravitational forces lead to orbits of closed…
Discusses the importance of general relativity to satellite mapping. How are satellites being used to determine natural resources such as deposits of iron, groundwater, and schools of fish, to name a few? Why does the gravitational force vary at different points in a satellite’s orbit? How does this relate to what you’ve studied about gravitation? Be sure to cite your sources.
Newton's Law of Gravity is what can we say about the law, and about G? Check the 4 correct statements. There will be partial credit if you miss some. We must find G by making precision experimental measurements because we do not know its value otherwise. All evidence suggests that It is the same everywhere, for all time Its value sets the "size" or "strength" of gravitational force We can calculate G from first principles and understand why it has the value it does. This law of gravity only works near Earth. In space far from Earth there is no gravity. It may not apply very close to very large masses where General Relativity takes over as a better description.
Summarize two observations that are contrary to the predictions based on Newton’s laws but that confirm Einstein’s explanation of gravity. Indicate how the predictions based on Newton’s theory differ from Einstein’s.
Using the GUFSA Template. Round off your final answer to the nearest hundredths. As we already know, rockets travel at very high speeds. How much time will it take a rocket (in seconds) to reach the moon if the moon is 238,900 miles away from the Earth, and the rocket is travelling 1,800,000 centimeters per minute? (express your answer in meters per second)
What Do You Already Know About Rockets? Think about how spacecraft change course once they are in space. Do spacecraft use rocket thrusters to maneuver in space, or are rockets only used to launch the spacecraft?
(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) - The first "Lunar Olympics" is to be held on the Moon inside a huge dome. Of the usual Olympic events—track and field, swimming, gymnastics, and so on—which would be drastically affected by the Moon's lower gravity? In which events do you think Earth-based records would he broken? In which events would the performances be no better—or perhaps worse— than on Earth?
You have negotiated with the Omicronians for a base on the planet Omicron Persei 7. The architects working with you to plan the base need to know the acceleration of a freely falling object at the surface of the planet in order to adequately design the structures. The Omicronians have told you that the value is gOP7=7.29 flurg/grom^2, but your architects use the units meters/second^2, and from your previous experience you know that both the Omicronians and your architects are terrible at unit conversion. Thus, it's up to you to do the unit conversion. Fortunately, you know the unit equality relationships: 5.24flurg=1meter and 1grom=0.493second. What is the value of gOP7 in the units your architects will use, in meter per second squared?
Astrology, that unlikely and pseudoscience, makes much of the of the at the The force that a planet could exerts gravitational, if there is anything to astrology we should expect this force to be significant Part A: calculated the gravitational force, in newtons , exerted on a 3.8 kg baby by a 105 kg father who is distance of 0.18 m away at the of its birth? Part b: Calculate the force on the baby, in newtonsdue to Jupiter (the largest planet, which has a mass of 1.90*10^ 27 kg) if it is at closest distance to Earth, 6.29 * 10 ^ 11 m away Part c: what is the ratio of the force of the father on the baby to the force of Jupiter on the baby
Please explain in full detail as I am trying to understand this concept! thank you! a. Sketch a diagram including Earth, Sun, and Mars, with attention to scale of distance (Mars is about 1.5 AU from the Sun) showing a faster trajectory from Earth to Mars than the minimal energy trajectory discussed in the lecture. b. Without doing a calculation, how would the arrival velocity of the spacecraft at Mars for the case in (a) compare to the spacecraft arrival in the class example? The lecture example had the spacecraft arriving at Mars with a velocity of 22.49 km/sec. c. The average velocity of Mars in orbit around the Sun is 24.08 km/sec. Comment on the trade-offs between trajectories, arrival velocities and velocity changes (delta V) required to enter an orbit around Mars.
