Chapter 13: GRAVITATION 1. In the formula F = Gm 1 m 2 /r 2 , the quantity G : A. depends on the local value of g B. is used only when Earth is one of the two masses C. is greatest at the surface of Earth D. is a universal constant of nature E. is related to the Sun in the same way that g is related to Earth ans: D 2. The magnitude of the acceleration of a planet in orbit around the Sun is proportional to: A. the mass of the planet B. the mass of the Sun C. the distance between the planet and the Sun D. the reciprocal of the distance between the planet and the Sun E. the product of the mass of the planet and the mass of the Sun ans: B 3. Suitable units for the gravitational constant G are: A. kg · m/s 2 B. m/s 2 C. N · s/m D. kg · m/s E. m 3 /(kg · s 2 ) ans: E 4. The gravitational constant G has the derived units: A. N · m B. N · m/kg C. N · kg/m D. N · m 2 /kg 2 E. N · kg 2 /m 2 ans: D 5. Earth exerts a gravitational force on the Moon, keeping it in its orbit. The reaction to this force, in the sense of Newton’s third law, is: Chapter 13: GRAVITATION 193

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
