What are the two categories of inertia?

  1. Static and dynamic

  2. Resting inertia and moving inertia

  3. Internal and external

  4. Potential and kinetic

The correct answer is: Resting inertia and moving inertia

The correct choice identifies the two categories of inertia as resting inertia and moving inertia. Inertia refers to the property of matter that causes it to resist changes in its state of motion. Resting inertia applies to an object that is not in motion, emphasizing its resistance to starting to move when a force is applied. Moving inertia, on the other hand, pertains to an object that is already in motion and its resistance to changing velocity or direction. Understanding this distinction is fundamental in the study of physics and athletics, as it applies to how forces interact with objects in motion or at rest. This concept is crucial when considering how athletes overcome inertia to move effectively, whether they are starting from a static position or changing direction while in motion. The other options do not correctly represent categories of inertia. Static and dynamic refer overall states of motion rather than specifically addressing inertia. Internal and external pertain to forces acting on a system rather than the existence of inertia. Potential and kinetic are forms of energy, not categorizations of inertia.
