Pure Translation Motion:
Pure translation motion refers to the motion in which an object moves from one position to another without any rotation. In this type of motion, all the particles of the object move parallel to each other with the same velocity and without any change in orientation. The object maintains its shape throughout the motion.

Example:
- When a car moves in a straight line on a road without any turning or rotating, it exhibits pure translation motion. In this case, all the wheels of the car move parallel to each other, and there is no rotation involved.

Pure Rotational Motion:
Pure rotational motion occurs when an object rotates about an axis without any linear displacement. In this type of motion, all the particles of the object move in circular paths around the axis of rotation. The object undergoes a change in its orientation but does not change its position.

Example:
- When a spinning top rotates about its fixed axis, it demonstrates pure rotational motion. In this case, all the particles of the top move in circular paths around the axis of rotation, but the top itself does not undergo any linear displacement.

Combined Motion:
Combined motion refers to the motion that involves both translation and rotation. In this type of motion, an object experiences linear displacement as well as rotational motion simultaneously. The particles of the object move both parallel to each other and in circular paths around an axis.

Example:
- When a football is kicked, it experiences combined motion. Initially, the football moves forward in a linear path (translation), but as it rotates due to the spin imparted by the kick (rotation), it also undergoes a change in orientation. The combined motion of the football involves both translation and rotation simultaneously.

Summary:
- Pure translation motion involves linear motion without rotation, where all particles move parallel to each other.
- Pure rotational motion involves rotation around an axis without linear displacement, where all particles move in circular paths.
- Combined motion involves both translation and rotation, where an object experiences linear displacement and changes in orientation simultaneously.
