Free-Fall Acceleration

Free-Fall Acceleration Free-Fall Acceleration An important example of straight-line motion with constant acceleration is that of an object rising or falling freely near Earth’s surface. The constant acceleration equations describe this motion, but we make two changes in notation:  (l) we refer the motion to the vertical y axis with +y vertically up; (2) we replace a with – …

Instantaneous Acceleration

Instantaneous Acceleration Instantaneous Acceleration Instantaneous acceleration (or simply acceleration} a is the rate of change of velocity with time and the second derivative of position X(f) with respect to time: On a graph of ~ versus I, the acceleration a at any time I is the slope of the curve at the point that represents f.
