Ans- Circular motion.

7. A body rotates about a axis passing through it then the motion is called ?
Ans- Rotary motion.

8. The motion in which a nut moves to and fro or back and forth repeatedly about a fixed point, then this motion is called ?
Ans- Oscillatory motion.

9. If in oscillatory motion, the amplitude is very small, then the it is said ?
Ans- Vibratory motion.

10. When the position of the object changes only in one direction or moves along a line then the motion is called ?
Ans- One-Dimensional motion.

11. When body move on a plane, then the motion said –
