- 3. Multiple ChoiceAs mass increases, what happens to gravitational force?increasesdecreasesstays the samei don't know
- 4. Multiple ChoiceAs the distance between 2 objects increases, what happens to gravitational force?increasesdecreasesstays the samei don't know
- 5. Multiple ChoiceWhich of the following will not change in different gravitational fields?wieghtforcemasspounds
- 6. Multiple ChoiceWhich of the following will change with different gravitational forces?massamount of matter in an objectweightkilograms
- 7. Multiple ChoiceA measure of gravitational force on an object.gravityweightmasskilograms
- 8. 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
- 9. Multiple ChoiceWhen an object is falling, and it reaches it's maximum speed because air resistance is equal to the force of gravity, the object has reached __________________________.Free FallTerminal VelocityProjectile MotionOrbit
- 10. Multiple ChoiceWhat force causes objects falling near Earth's surface to slow down?GravityAir ResistanceCentripetal ForceNewtons
- 11. 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.
- 12. Multiple Choice
When a parachute canopy is opened more drag is created because:
It has a large mass
It has a large surface area
It is travelling at terminal speed
The person is now vertical
- 13. Multiple Choice

when the masses of both objects are small and the objects are far apart
when the masses of both objects are large and the objects are close together
when the masses of both objects are small and the objects are close together
when the masses of both objects are large and the objects are far apart
- 15. Multiple Choice
Which statement about gravity is true?
gravity causes objects to pull towards one another
gravity causes objects to push away from each other
gravity only takes place between planets
the moon doesn't have any gravity
- 16. Multiple ChoiceWhat is the SI unit used to measure force?poundsgramsnewtonskg/ m2
- 17. Multiple ChoiceAny object with mass is surrounded by a gravitational field.TrueSometimesFalseNever
- 18. Multiple ChoiceWhich of the following will not change in different gravitational fields?weightforcemasspounds
- 19. Multiple ChoiceWhich model has greater gravitational attraction (if any)Model AModel BBoth Model A and Model B (same gravity)
- 20. Multiple ChoiceA person would weigh more on Jupiter than on the Earth because . . .Jupiter has more mass, and therefore more gravityJupiter has less mass, and therefore more gravityJupiter has more mass, and therefore less gravityJupiter has less mass and therefore less gravity
