The video tutorial explains the concept of inertia, using two examples to illustrate how objects resist changes in their state of motion. The first example involves passengers on a bus who lurch forward when the bus stops suddenly, demonstrating the need for seatbelts. The second example shows a boy holding coins that fall when he stops abruptly, as the coins continue moving forward due to inertia. The video concludes with a clear explanation of inertia as a force that maintains an object's motion unless acted upon by an external force.
