2. Scope of motion Within the scope of the study of motion are many different concepts.

3. Displacement While distance and displacement are commonly used interchangeably, it is important to note that displacement is a vector quantity that describes a change in position as illustrated by the Pythagorean theorem.

7. Two dimensional motion examples: Trajectories or ballistic motion

8. Two dimensional motion examples: Rotation- complex enough to study separately

10. Relative motion Trains Often, things change position with respect to time and another moving object. This is the principle of relative motion.
