Right-hand rule determines vector direction in three-dimensional space. Rule uses thumb and fingers to represent vector components. Works only with right hand, opposite direction with left hand
Rotation is circular movement around a central axis. Plane figures can rotate clockwise or counterclockwise around perpendicular axes. Solid figures have infinite possible axes and angles of rotation. Rotation keeps at least one point fixed unlike translation
Rotation around fixed axis is a special case of rotational motion. Simultaneous rotation along multiple stationary axes is impossible. Rotation around fixed axis is mathematically simpler than free rotation

Moment of inertia is the tendency of a body to resist rotational motion changes. It is measured in kgm² and is a scalar quantity. Moment of inertia depends on shape, size, material density and rotation axis
Moment of inertia measures rotational inertia relative to fixed axis. SI unit is kg·m², imperial units are lb·ft·s² or lb·ft². Always positive value, cannot be negative
