Gravity
Gravity

Free fall acceleration at sea level in meters per second squared. This is the standard gravity constant 9.80665. The gravity in your particular neck of the woods might be different due to different altitude and the fact that the earth is not perfectly round and uniform.

e
e

The base of the natural logarithm. e^x is the exponential function exp. It is approximately 2.71828182846... This number is sometimes called Euler's number, although there are several numbers that are also called Euler's. An example is the gamma constant: EulerConstant.
