- 8. Multiple Choice
If an object is free falling onto the Moon, which of the following would be correct?
It would accelerate at 9.8 m/s2
It would not encounter any air resistance.
It would not fall because the Moon has no gravity.
It would impact the surface and bounce back into space.

Multiple ChoiceDo free falling objects move at constant velocity or do they accelerate?Falling objects accelerate at -9.8 m/s2Falling object move at constant velocityFalling objects accelerate at 100 m/s2It depends on the mass: heavy objects accelerate, light objects do not
- 20. Multiple ChoiceWhat values are always known for a free falling object?vi = 0 m/s
a = -9.8 m/s2vi = -9.8 m/s
a = -9.8 m/s2vi = -9.8 m/s
