The acceleration due to gravity is actually (nearly) constant at 9.81m/s^2. If you take air resistance into account, the effective acceleration decreases. The velocity however increases, but not exponential, it is a linear increase (again if you neglect air resistance). The only exponential part is when you are reaching terminal velocity when accounting for air resistance (because that is the reason for terminal velocity). Probably you speak of thr accelaration that occurs when you hit the ground. Assuming that the time to stop is constant, the force is also only growing linearly, which is no miracle, because the forumar for the potential energy is linear with the height.</blockquote>
