2. MOTION
• A CHANGE IN POSITION OF AN
OBJECT OVER TIME IS KNOWN
AS MOTION.

3. CONCEPT OF REST AND
MOTION
• Concept of rest and motion represented by a
frame of reference.
• Frame of reference

4. TYPES OF MOTION
• THERE ARE FOUR TYPES
i)LINEAR MOTION
ii) CIRCULAR MOTION
iii) ROTATIONAL MOTION
iv)VIBRATORY MOTION

5. LINEAR MOTION
• An object moves in a straight line
is known as linear motion.

6. EXAMPLES

7. CIRCULAR MOTION
An object
moves in a
circular path

8. EXAMPLES
I)Rotation of clock
ii)Rotation of earth
iii)Roation of fan

9. VIBRATORY MOTION
If an object or particle executes to
and fro motion about a fixed point ,
it is said to be in vibratory motion.

10. EXAMPLE
• The stretched string
• The motion of the swing
• Simple pendulum

11. OSCILLATORY M0TION

12. SIMPLE PENDULUM

13. MOTION IN ONE DIMENSION
• It is the motion of the particle
moving along the straight line.
• Example:
• Motion of a train along the straight
railway track.
• An object falling freely under gravity.

14. MOTION IN TWO DIMENSION
• If a particle moving along a curved
path in a plane then it is said to be in
two dimensional motion.
• Example:
• Motion of a carrom coin.

15. MOTION IN THREE DIMENSION
• A particle moving in a usual three
dimensional space has three
dimensional motion.
• Example :
•A bird flying in the sky.
•Random motion of a gas molecule.

16. SCALAR AND VECTOR
SCALAR
• It is a property which can be described
only by magnitude.
VECTOR
• It is a quantity which described by both
magnitude and direction.

17. TYPES OF VECTORS
• Equal vectors
• Collinear vectors
• Orthigonal vectors

18. ADDITION OF VECTORS
