Notes
This study was conducted to compare growth mechanics between logistic functions and basic growth functions. The results obtained were as follows. Differential equation for basic growth function showed that the square of growth rate was described using the product of weight and growth acceleration. This form was similar to Newton's law of motion where differential of momentum is described using the product of mass of an object and acceleration. However, differential equation for logistic function took a form that was more complex, due to the existence of additional function, than that for basic growth function. Therefore, only the product of weight and growth acceleration was not sufficient to describe the square of growth rate in the differential equation for logistic function. This insufficiency was compensated by the additional function. This is one of the reasons why logistic functions are more complex than basic growth functions showing increases only. It was suggested from the present study that growth mechanics of logistic functions was more complex than that of basic growth functions.
