Question

1-Which is true about the acceleration due to gravity on Earth?

A-It is a universal constant.
B-It can only act through a short distance.
C-It decreases with increasing altitude.
D-It is different for different objects in free fall.

Answer 1

Answer: C -- decreases with increasing altitude

Step-by-step explanation:

A--g is different on other planets and objects like asteroids, etc. It is 9.8 m/s2 only on Earth

B--g acts on long distances, too, not just short

D--g is independent of the mass of the free falling object

C is correct. The value of g decreases the higher you go in altitude
