The standard acceleration due to gravity (or standard acceleration of free fall),is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth. It is defined by standard as:
9.8 m/s.
9.8 m.
9.8 m/s2.
9.8 s.
Free fall takes into consideration the frictional force of air resistance.
True
False

19.6 m/s
29.4 m/s
39.2 m/s
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.
