```The formula for calculating the excellaration of a falling object is
D=.5a*t^2
D is distance, a is acceleration
T is time
On earth, the acceleration is 32 feet per second per second.
On the moon the accelerationis 32/6 or 5.33333feet per second per second
Now plug the numbers into the variable a and devide by 2 for the earth it will give you 16
For the moon that will give you 2.666
Now if you let a object fall for 2 seconds on the earth that will be 2 squared or 4. Now multiply 4 times 16 which will give you 64 feet so in 2 seconds a object will fall 64 feet on the earth. Bythe way the object will be falling 64 feet per second at that point as well.
Now the moon.
Let a object fall for 2 seconds on the moon.
So we square the time which is 2. So that will be 4.
Now multiply 4 times 2.666 and you will get  10.664
So on earth a object will fall 64 feet in two seconds.
On the moon the object will fall 10.6 feet in two seconds.
Here we are dropping the object in a vaccume on the earth as it will be on the moon.
Hope that helps.

Hi all!
I’m looking for ideas on how to compare the gravity of the earth to the gravity of the moon. The moon is one sixth the gravity of the earth. Does anyone have ideas on how to show the gravity from both the earth and the moon?

Thank you for taking the time to read this E Mail!
Blessed be!!!
