The brick falls to the ground.
 
Gravity  pulls upon the brick, causing it to go faster and faster.
The distance between the brick and  where it was released
after t seconds is:
distance = (1/2)*G*t2
tis the number of seconds since the brick was released.
Gis a constant: 9.80665
distanceis in meters.
After 0.0 seconds, the brick has dropped 0.0 meters.
After 1.0 second, the brick has dropped 
After 2.0 seconds, the brick is  has dropped 
After 3.0 seconds, the brick is  has dropped 
This is getting tedious. Let's write a program that does the
calculation for many values of t and prints the results as a table.
Let's use a loop.
