Velocity Function: Function that describes the rate of change of position with respect to time. It is found by integrating the acceleration function.
Acceleration Function: Function that describes the rate of change of velocity with respect to time. For a falling object, it often includes gravitational acceleration and air resistance.
Fundamental Theorem of Calculus:\( \text{Links differentiation and integration; states that if } F(x) \text{ is an antiderivative of } f(x), \text{ then } \int_a^b f(x) \, dx = F(b) - F(a). \)
