1) Why does the object in the middle move toward object B? a) B has more mass b) It has less mass  c) Its closer d) Its further  2) How does the mass of an object affect gravity? a) More mass, less gravity b) Less mass, more gravity c) More mass, more gravity d) Mass has no effect on gravity 3) According to the law of gravity, what happens if you move two objects closer together? a) Gravity increases b) Gravity decreases c) Gravity stays the same d) No gravity at all 4) If distance INCREASES, what happens to the force of gravity? a) It doubles b) It decreases c) it increases d) its zero 5) Why does the little blue dot move toward object B? a) the blue dot has more mass, so it has more gravity b) object B has less gravity c) it's closer, therefore gravity increases  d) its further away, so gravity increases 6) What two factors affect gravity? a) Mass & Distance b) Distance and Inertia c) Inertia and Volume d) I HAVE NO CLUE BECAUSE I DIDN'T STUDY SO ILL PROBABLY MAKE A 67 ON THE TEST 7) Which change would cause the GREATEST increase in gravity? a) Increasing mass and decreasing distance b) Decreasing mass and increasing distance c) Decreasing both d) Adding moons 8) How does inertia behave in space? a) Inertia is stronger in space than on Earth. b) In space, objects do not exhibit inertia. c) Inertia in space causes objects to resist changes in their motion. 9) If the distance between two objects increases, gravity will… a) Increase b) Decrease c) Stay the same d) Nothing will happen 10) Which best explains why planets stay in orbit around the Sun? a) Only inertia b) Because of the moon c) Gravity and inertia working together d) Because of Earth 11) Inertia is best described as… a) The tendency of an object to resist changes in motion b) The speed of an object c) The force pulling objects together d) The path an object follows 12) An astronaut on the Moon weighs less than on Earth because… a) Space removes weight b) The astronaut’s mass is smaller c) The Moon has no gravity d) The Moon has less mass and weaker gravity 13) If the gravitational force between a planet and the Sun becomes weaker, the planet’s orbit speed will MOST LIKELY: a) slow down b) reverse c) stay the same d) speed up
