Describing Free Fall Video Tutorial

The Describing Free Fall Video Tutorial defines free fall and describes the changes (or lack of changes) in the position, velocity, and acceleration over the course of a free fall motion. Numerical data, dot diagrams, vector diagrams, and velocity-time graphs are presented for both falling and up-and-down motion. The video emphasizes the meaning of the free fall acceleration. The video lesson answers the following questions:

1. What is meant by free fall or free-falling motion?
2. How can the position, velocity, and acceleration be described during the course of a free fall motion?
3. How can the velocity of an object be calculated at any given instant in time?
