- 1. Multiple Choice
Which objects have a STRONG force of gravity?Objects with GREATER mass, like elephantsObjects with LESS mass, like mice - 2. Multiple ChoiceWhat is the SI unit used to measure force?poundsgramsnewtonsfriction
- 3. Multiple ChoiceAs distance between two objects increase the pull of gravityIncreasesDecreasesStays the same
- 4. Multiple ChoiceThe force of gravity acting on an object is the object's ______.massmatterweightfriction
- 5. Multiple ChoiceThe amount of matter in an object ispressureweightmassforce
- 6. Multiple ChoiceWhich of the following never changes no matter where in the universe?weightforcemasspounds
- 7. Multiple ChoiceA person would weigh less on on the Moon than on the Earth because . . .Moon has more mass, and therefore more gravityMoon has less mass, and therefore more gravityMoon has more mass, and therefore less gravityMoon has less mass and therefore less gravity
- 8. Multiple ChoiceTwo factors effecting the magnitude of the force of gravity between 2 objects are...mass and distancemass and matterdistance and weightweight and mass
- 9. Multiple ChoiceIf Earth's mass was cut in half, what would happen to your mass?increase because gravitational force increasesdecrease because gravitational force decreasesdecrease because gravitational force increasesnothing, mass is not affected by gravitational force

- 12. Multiple ChoiceAs mass increases, what happens to gravitational force?increasesdecreasesstays the samei don't know
- 13. Multiple ChoiceWhich model has greater gravitational attraction (if any)Model AModel BBoth Model A and Model B (same gravity)
- 14. Multiple ChoiceWhich system has the greater gravitational attraction between the two objects (if any)?System ASystem BSame gravitational attraction fro System A and System B
- 15. Multiple ChoiceHow does changing the distance of the string in the model represent the orbits of the planets?the longer the string means the larger the planetthe longer the string, the longer the orbit time of a planetthe shorter the string, the longer the orbit time of the planetthe shorter the string, the smaller the planet
- 16. Multiple ChoiceWhat best describes the mass and weight of a person as they move around the universe?mass and weight changesMass and weight stays constantweight remains constant, mass changesMass stays constant, weight changes
- 17. Multiple ChoiceThe force of gravity on Jupiter is a little more than 2 times the gravitational force on Earth. If an object has a mass of 50 kg and a weight of 490 N on Earth, what would be the object's approximate mass and weight on Jupiter?50 kg and 490 N100 kg and 490 N50 kg and 980 N100 kg and 980 N
- 18. Multiple ChoiceWhen only the force of gravity is acting on an object, we say that the object is in ___________________________.Terminal VelocityFree FallProjectile motionCentripetal Force
- 19. Multiple ChoiceWhat force causes objects falling near Earth's surface to slow down?GravityAir ResistanceCentripetal ForceNewtons
- 20. Multiple ChoiceIf a bowling ball and a feather were dropped at the same time, in a room with no air resistance (vacuum), which object will hit the ground first?Bowling BallFeatherBoth would hit at the same timeNeither one would hit the ground because air is what pushing things down.
