Center of Mass:

The center of mass is the point in a system where the total mass can be considered to be concentrated. It simplifies calculations involving motion and forces acting on an object.

Torque:

Torque is a measure of how effectively a force causes rotation around an axis. It depends on both the magnitude and direction of the force relative to the axis.

Moment of Inertia:

The moment of inertia measures an object's resistance to changes in rotational motion. It depends on both the mass distribution and shape of the object.
