Physics Mop Test CG6-CG10 According to Newton's law of universal gravitation, which of the following pairs of objects would not experience a mutual force of gravitation? - Nonsense! All objects experience a mutual force of gravitation The force of gravitation between objects is? - Always an attractive force The force of gravitational attraction between any two objects is? - -Directly proportional to the product of their masses - Inversely proportional to the square of the distances between their centers The force of gravitational attraction between the Sun and a Planet is dependent upon? - -The mass of the Sun -The mass of the Planet -The distance between the planet's center and Earth's center Suppose that an object weighs 60N on the surface of the Earth (a distance of R from its center). If the same object is located a distance R above the Earth's surface (a distance of 2R from its center, then the force of gravity upon it would be? - 15.0 Suppose that an object weighs 20N on the surface of the Earth (a distance of R from its center). If the same object is located a distance R above the Earth's surface (a distance of 3R from its center, then the force of gravity upon it would be? - 2.22 There is much talk about Isaac Newton's law of universal gravitation and the falling apple. The significance of the apple was that Newton? - Compared the Earth's gravitational pull on the apple to Earth's pull on the moon Isaac Newton is credited with the law of universal gravitation. One of the major elements of Newton's discovery (that had not yet been recognized) was the recognition that the force that causes the apple to fall to the Earth is? - The same force that causes any two objects in the universe to attract each other The acceleration of gravity (g) refers to the? - Rate of acceleration of an an object that is acted upon solely by gravity Two objects are located at different locations about two planets with the distinctly different masses. Compared to location A, the acceleration of gravity value at location B is? - The same magnitude The acceleration of gravity on the surface of the Earth is 9.8 m/s/s. As one moves increasingly further from the surface of the Earth, the acceleration of gravity value? - Decreases An astronaut is on the orbiting space shuttle, approximately 60 miles (^ 100,000 meters) above the surface of the Earth. (The Earth's radius is approximately 6,360,000 meters and its mass is (^ 5.98x10^24 kg.) At this location, one might predict the acceleration of gravity to be? - A small percent less (1-10%) Increasing order - 0.5 (two arrows), 2M (two arrows), M (one arrow), and 2M (one arrow) M (one arrow) compared to 2M (two arrows) - 1/2 An object of mass 'M' is located a distance 'R' from the center of a planet with a mass 'M'. The g value at this location is 12 m/s/s. Suppose that the mass of the object is doubled to '2M' and the seperation distance is doubled to '2R'. The new g value would be? - 3 m/s/s The acceleration of gravity upon Mars' surface is 3.75 m/s/s. At a location of 'R' above Mars' surface (where 'R' is the radius of of the Mars), the acceleration of gravity is closet to? - 0.94 m/s/s The acceleration of gravity upon Mars' surface is 9.8 m/s/s. At a location of 'R' above Mars' surface (where 'R' is the radius of of the Mars), the acceleration of gravity is closet to? - 2.45 m/s/s The acceleration of gravity upon Mars' surface is 13.30 m/s/s. At a location of 'R' above Mars' surface (where 'R' is the radius of of the Mars), the acceleration of gravity is closet to? -
