Question 1 of 5
###### Universal Gravitation

Newton's Law of Univeral Gravitation defines the general formula for the attraction of gravity between two objects: $$\vec{F_{g}} = { Gm_{1}m_{2} \over r^2}$$ . In the specific case of an object falling toward Earth, the acceleration due to gravity (g) is approximately 9.8 m/s2.

On Earth, acceleration due to gravity (g) is approximately __________.

 1 m/s 1 m/s2 6.67 x 10-11 m/s2 9.8 m/s2
