Acceleration increases. If the Earth were moved to half its current distance from the Sun, how would the force of gravity by the Sun on the Earth change? It would become four times stronger. What did Newton's Law of Universal Gravitation tell us about how gravity works? The force of gravity from the Sun will be stronger on an object with more mass? 4 According to Newton's Second Law of Motion, if the net force acting on the object increases while the mass of the object remains constant, what happens to the acceleration? Don't know? 12/18/24, 7:26 PM ASTRO 001 Unit 1 Quiz EXAM PRACTICE QUESTIONS AND ANSWERS 100% PASS GUARANTEED Flashcards | Quizlet The Earth's radius is about 6400 km. If you were in orbit in the Space Station 150 km above the ground, the force of gravity you feel from Earth would be? Slightly weaker than when you are standing on Earth. If you were to sit on the ground, there would be a force due to gravity pulling you toward the Earth. According to Newton's 3rd law what is going on? You are pushing the Earth away from yourself with the same force. What would happen to the Earth if the Sun's gravity somehow turned off instantaneously? It would continue to move in a line in the same direction it was moving when the gravity turned off. Consider a planet whose rotation is not tilted with respect to its orbital place. What are the seasons like on this planet? There are no seasons. If the Earth rotated on its axis more slowly than it does now... its days would be longer. 12/18/24, 7:26 PM ASTRO 001 Unit 1 Quiz EXAM PRACTICE QUESTIONS AND ANSWERS 100% PASS GUARANTEED Flashcards | Quizlet If the Earth had its orbit changed so that at all points along its orbit it was always the same distance from the Sun, how would this affect the seasons on Earth? They would be the same as they are now. A new planet orbits its star faster than the Earth orbits the Sun and it rotates more slowly than the Earth, what can be said about its year and day? It has a shorter year and longer day than Earth. What time of year is it dark all day (and night) at the South pole? June. If Earth's moon was full on May 1, 2007, when was it next in the first quarter phase after this full moon? May 22. How much of the total surface area of the moon is illuminated by sunlight during the full moon phase? 1/2 of it. At approximately what time does the third quarter moon rise? Midnight. 12/18/24, 7:26 PM ASTRO 001 Unit 1 Quiz EXAM PRACTICE QUESTIONS AND ANSWERS 100% PASS GUARANTEED Flashcards | Quizlet Approximately two weeks after a Sole Eclipse, what phase will the moon be in? Full A moon orbits a planet in exactly the same plane as the planet orbits its star. How often does this planet experiences a solar eclipse? Once every orbit of its moon, or each month. From Earth, in which constellation might you find the planet Saturn? Taurus Why don't we see the constellation Orion at night all throughout the year? As the Earth orbits the Sun, its nighttime side points to different constellations at different points along its orbit. When is the best time for you to be able to see the constellation that is your sign of the Zodiac? At midnight six months after your birthday. Constellations close to the North pole of Earth...? Move in a circle around the North star, Polaris, over the course of a single night.
