What is Acceleration Due to Gravity?

The acceleration due to gravity is known of Earth to be 9.8 meters or 32 feet per second squared. If all other factors were constant, then free fall velocity to the surface would increase by the square of the seconds times 9.8 or 32. For example, after one second you would be falling at a rate of 32 feet per second but after two seconds you would be falling at a rate of 128 feet per second and so on.
