Types of Motion and Speed

The video tutorial explains the concepts of motion and rest, highlighting that they are relative terms. It covers linear motion and various types of motion such as circular, periodic, oscillatory, and random. The tutorial differentiates between distance and displacement, emphasizing their definitions and units. It also discusses uniform and non-uniform motion, providing examples and explaining the differences. Finally, the concept of speed is defined, with a practical example of calculating speed using distance and time.
