What about near a small marble?arrow_forwardKepler’s third law says that the orbital period (in years) is proportional to the square root of the cube of the mean distance (in AU) from the Sun (Pa1.5) . For mean distances from 0.1 to 32 AU, calculate and plot a curve showing the expected Keplerian period. For each planet in our solar system, look up the mean distance from the Sun in AU and the orbital period in years and overplot these data on the theoretical Keplerian curve.arrow_forwardMust engineers take Earth’s rotation into account when constructing very tall buildings at any location other than the equator or very near the poles?arrow_forward
- Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?arrow_forwarda) Sketch the earth and mars, showing the center of the planets being separated by a distance d = 3 x 10^11 m. b). Use Newton's Universal Gravitation equation to determine the gravitational force of attraction between earth and mars at that distance given G= 6.7 x 10^-11 N x m^2/kg^2, mass of earth = 6 x 10^24 kg, mass of mars = 6.4 x 10^23 kgarrow_forwardNewton’s law of gravitation and the formula for centripetal acceleration can be used to show that: T^2=(4π^2/Gms)R^3 where G is the universal constant of gravitation and MS is the mass of the Sun.

- 1) Calculate the tidal force (the difference in gravitational force from right to left side or G(R) - G(L) ) from a person sitting next to you (approximately 1 meter away). You will need to make some estimations on mass and size of a normal person. 2) Compare the tidal force on a person from the Moon and a person standing nearby (the answers to the previous two questions). Which is greater and by how much?arrow_forwardA satellite is geostationary if it appears fixed in the sky as seen by an observer on Earth. Geostationary satellites are very useful for communication and a lot of them are in use. Access to geostationary orbit is regulated by international treaty and a spot in geostationary orbit is probably the most desirable "unreal estate" I can think of. What goes into making an orbit geostationary? Kepler's and Newton's laws, and location, location, location. We will determine how this works in these exercises. Kepler's first law in this context states that the orbit of a satellite is an ellipse with the center of the Earth at one focus. Kepler's second law states that the line joining the satellite and the center of the Earth sweeps out equal areas in equal intervals of time. Kepler's third law (in Newtonian form) relates the orbital period of the satellite to the semi-major axis of the orbit and the mass of the Earth. In order to appear geostationary, a satellite must have a circular orbit,…arrow_forwardSuppose humans are successful in living on the moon. They would need GPS just like on Earth to be able to navigate to “Moonmart”. They launch a 500 kg satellite in a geosynchronous orbit around the moon. Assume the Moon’s mass is 7.35x1022 kg.The moon takes 708.7 hours to make 1 rotation, or 2,551,320 seconds. What is the satellite’s orbit radius? What is the satellite’s orbit speed? After 20 years, a newer GPS satellite is built, and they want to get rid of the old one. How much energy is needed for the original satellite to escape its moon orbit?arrow_forward
- Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion. Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU. Does this make physical sense? Explain why or why not.arrow_forwardUse a distance of R = 1.48x10^11 meters for the distance between the earth and the sun. Use a mass of 1.99x10^30 kg to be 1 solar mass. For each of the different sun masses (as values of solar mass, aka 0.5 solar masses = 1x10^30 kg), as outlined in the lecture, calculate the period of the earth's orbit in days using Kepler's law for circular orbits (I double-checked it with these values and it works) and also calculate the corresponding orbital velocity of the earth. Questions: 1.) Using these values, and 6x10^24 kg for the mass of the earth, what is the strength of the gravitational force between the earth and the sun? 2.) If the earth were twice as far from the sun, what would be its period of orbit? 3.) Mars orbits the sun at a distance of 2.18x10^11 meters.
