In this paper, we used q-deformed variational calculus to construct the q-deformed version for classical mechanics. We used the q-deformed derivative and the q-deformed integral to study the motion with constant velocity and the motion with constant acceleration, and we extended our work to the motion of a body in a resisting medium, in which the retarding force was assumed to be proportional to the q-deformed velocity. We found that the ordinary exponential function was replaced with the q-deformed exponential function for the first order q-deformed differential equation such as terminal velocity problem. We also dealt with the damped oscillator problem by using the second-order q-deformed differential equation. In that case, we found new kinds of q-deformed exponential functions.
