Why do the blobs behave as they do when Dr. Hewitt turns?

The behavior of the blobs when Dr. Hewitt turns is primarily due to inertia, which is a property of matter that causes it to resist changes in its state of motion. In this scenario, when Dr. Hewitt turns, the blobs experience a tendency to stay in their original straight-line path due to their inertia. This means that as the turning motion occurs, the blobs do not immediately follow the turn but rather continue in the direction they were moving before the turn, resulting in an apparent lag or displacement relative to Dr. Hewitt.

This concept can be illustrated by Newton's First Law of Motion, which states that an object at rest stays at rest and an object in motion continues in motion at a constant velocity unless acted upon by a net external force. The blobs' motion reflects this principle, demonstrating how inertia influences their behavior during the turning motion. Understanding inertia enables us to predict and explain the unexpected motion of the blobs when changes in direction occur.
