What acceleration does the force of earth's gravity produce

it varies depending on how long it has been falling.
it changes direction every 9.8 meters
9.8 m/s/s
gravity does not produce an acceleration

9.8 m/s/s

Explanation:

The acceleration produced by Earth's force of gravity is approximately 9.8 m/s^2. Mathematically, the acceleration due to gravity is:

a = F/m

where:

a = acceleration due to gravity in m/s^2

F = force exerted in Newton

m = mass in kg

The equation shows that acceleration is directly proportional to force and inversely proportional to mass. Thus, the value of the acceleration due to gravity can be varied by changing either the force or the mass. Therefore, the correct option is 9.8 m/s/s.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
