Motion is the change in position of an object over time relative to a reference point. There are several types of motion including translatory, circular, oscillatory, and periodic motion. Translatory motion is motion in a single direction and can be rectilinear, in a straight line, or curvilinear, along a curved path. Circular motion involves movement around a fixed central point and can be rotatory, involving part of a body, or revolutionary, involving the whole body. Oscillatory motion is a back-and-forth movement, while periodic motion repeats at regular time intervals.

4. MOTION
It is the change of position of a
body in particular time with
reference to a stationary body

5. Type of Motion
 Translatory Motion
 Circular Motion
 Oscillatory Motion
 Periodic Motion

6. TRANSLATORY MOTION
It is the motion of a body in one direction.
Two types of translatory motion,
1. Rectilinear Motion
2. Curvilinear Motion

7. 1. RECTILINEAR MOTION
It is the motion of a body in a straight line.
Example :- Motion of car in straight road.

8. 2. CURVILINEAR MOTION
It is the motion of a body in a curved line
Example:- Running race in curved track

9. CIRCULAR MOTION
It is the motion of a body in circle round a
fixed point in centre.
Two types of circular motion are
1. Rotatory Motion
2. Revolutionary Motion

10. 1. ROTATORY MOTION
In this motion part of a body occupies a
particular position at a time.
Example:- Rotation of earth round sun.

11. 2. REVOLUTIONRY MOTION
In this motion the whole body move in
circular path around fixed point
Example:- Revolution of earth.

12. OSCILLATORY MOTION
It is the to and fro motion of a body
Example:- Motion of Swing
Movement of bob of pendulum

13. PERIODIC MOTION
It is the Motion that repeats after equal
interval of time.
Example:- Motion of planets
Motion of needles of clock
Rotation and revolution of earth.
