This document discusses different types of motion including rectilinear, curvilinear, and circular motion. It defines key concepts related to motion such as time period, speed, and periodic motion. Rectilinear motion refers to motion along a straight line, while curvilinear motion is along a curved line. Circular motion occurs along a circle. Time period is the time taken to complete one oscillation, and periodic motion repeats at fixed time intervals. Speed is the distance covered per unit of time and can be uniform or non-uniform. Common units of speed include meters/second and kilometers/hour.

2. OBJECTIVESOBJECTIVES
Motion involves a change in the position of
an object over time.
Motion can be described using
mathematical relationships.
Many technologies that apply concepts
related to kinematics have societal and
environmental implications

3. MotionsMotions
 When an object changes its position with
elapse of time in respect to a stationary
object, such as a building, electric pole, etc.,
the object is said to be in motion.

4. MotionMotion

5.  Rectilinear Motion: Motion along a
straight line is known as
RECTILINEAR motion or motion
along a straight line. For example:
Motion of a car along a straight line.

6.  Curvilinear Motion: Motion along a curve
line is known as curvilinear For example:
Motion of car or any moving object along a
curve line.

7.  Circular Motion: Motion along a circle is
known as circular motion. For example:
Motion of cyclist along a circular park.

8. Slow and Fast Motion: If an object ‘A’
covers a distance in less time and
another object covers the same distance
in more time, the object A is called a
faster moving object and object B is
called a slower moving object. In
other words, object A has faster
motion and object B has slower motion.

9. Time

10.  Time Period: Time taken to complete
one oscillation by the pendulum is called
time period.

11. Unit of Time: Time is measured in
second. Unit of time is second. Second is
denoted by ‘s’.
60 second = 1 minute
60 minute = 1 hour
24 hour = 1 day
7 day = 1 week
365 days = 1 year

12.  Periodic Motion or Oscillatory
Motion: When an object repeats its
motion after every fixed interval of time,
the motion of the object is called
periodic motion or oscillatory motion.
 In many wall clocks pendulum is used
even today. A device having a string
suspended with a fixed point with a bob
at bottom is called pendulum.

13.  The motion of pendulum starting from one
extreme end to another extreme end and
back to the first extreme end is called one
oscillation. Similarly, the motion of a simple
pendulum from its mean position to extreme
left and extreme right and back to the mean
position is called one oscillation.

14. Review Question:
A pendulum takes 20 second
to complete 10 oscillations,
calculate its time period.

15. Solution:Solution:
Number of oscillations = 10
Time taken = 20 second
We know that,

16. SpeedSpeed

17. Speed: Distance covered by an object in
unit time is called speed.
Uniform Speed: If an object covers a
fixed distance in each unit of time the motion
is known as uniform motion or uniform
speed.
Non-uniform Speed: If an object does not
cover a fixed distance in each unit of time
the
motion is known as non-uniform motion or
non-uniform speed.

18.  Unit of speed: Units of speed are
• Meter / second
• Meter / minute
• Kilometer / hour

19.  Speedometer: A device used to
measure the speed of a vehicle is
called speedometer.

20.  Odometer:A device used to measure
the distance covered by a vehicle .
