If the axis of rotation passes through the body and the body moves around then the motion is called:
- A
Spin motion
- B
Orbital motion
- C
Rectilinear motion
- D
Translatory motion
Spin motion is the motion of an object as it rotates around an axis through its center of mass. Example: rotational motion of earth
Spin motion occurs when an object rotates around an axis that passes through its own body, typically its center of mass. An example of this is the Earth rotating on its own axis.
Orbital motion involves an object moving in a path around an external point or body, such as the Earth orbiting the Sun.
Rectilinear motion refers to movement along a straight line, such as a car driving along a straight road.
Translatory motion is when the entire body moves in a uniform direction without rotation, such as a sliding box.
