Introduction to Inertia and Inertial Mass

The video tutorial explains the concepts of inertia and mass. Inertia is defined as the tendency of an object to resist changes in its state of motion, which is essentially resistance to acceleration. Mass is described as a measure of inertia, indicating that objects with more mass resist acceleration more. A practical example is provided using a desk and a chair to illustrate how mass affects motion. The video also touches on the concept of inertial mass and gravitational mass, noting that they are experimentally identical.
