State Newton's law of universal gravitation. - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\



ANSWERS ✔✔every object in the universe attracts every |\ |\ |\ |\ |\ |\ |\ |\



other object; anything that has mass has gravity
|\ |\ |\ |\ |\ |\ |\




The gravitational force of attraction between two objects
|\ |\ |\ |\ |\ |\ |\ |\



depends on _____________ and ____________. - CORRECT
|\ |\ |\ |\ |\ |\ |\



ANSWERS ✔✔mass; distance |\ |\




True or false? Gravity is the weakest universal force, but it
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



is the most effective force over long distances. -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



CORRECT ANSWERS ✔✔true |\ |\

, The sun's mass is much greater than the mass of Earth,
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



so the sun's gravitational force is much ____________ than
|\ |\ |\ |\ |\ |\ |\ |\ |\



that of Earth. - CORRECT ANSWERS ✔✔stronger
|\ |\ |\ |\ |\ |\




Why does the moon orbit Earth in a nearly circular path? -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



CORRECT ANSWERS ✔✔the moon's inertia and
|\ |\ |\ |\ |\ |\ |\



centripetal force from Earth produce the nearly circular |\ |\ |\ |\ |\ |\ |\ |\



path


True or false? The gravitational pull of the
|\ |\ |\ |\ |\ |\ |\




moon is the primary cause of Earth's ocean tides. -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



CORRECT ANSWERS ✔✔true |\ |\




True or false? The pull of Earth's gravity can slow an

artificial satellite, causing it to lose altitude and fall from
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



the sky. - CORRECT ANSWERS ✔✔Both. If the altitude was
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



low the answer would be true. If the altitude was high the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



answer would be false. |\ |\ |\
