3. Definition
In physics, motion is the change in position of an
object with respect to its surroundings in a given
interval of time.

4. Introduction
The motion of an object with some mass can be
described in terms of the following:
• distance
• displacement
• speed
• velocity
• time
• acceleration

6. Laws of Motion
Newton’s Laws of Motion laid the foundation for
classical mechanics today. Although subject to
minor limitations, these laws of motion are valid
everywhere and are therefore used. The laws are
given as stated below in a brief description
• First Law: Any object will remain in its existing
state of motion or rest unless a net external
force acts on it.

7. Laws of Motion
Second Law: If an object has a certain mass, the
greater the mass of this object, the greater will
the force required to be to accelerate the object.
It is represented by the equation F = ma, where
‘F’ is the force on the object, ‘m’ is the mass of
the object and ‘a’ is the acceleration of the
object.
Third Law: For every action, there is an equal and
opposite reaction.

8. Types of Motion
Uniform Motion:
• This type of motion is defined as the
motion of an object in which the object
travels in a straight line and its velocity
remains constant along that line as it
covers equal distances in equal intervals
of time, irrespective of the duration of the
time.

9. Types of Motion
If a body is involved in rectilinear motion and
the motion is consistent, then the
acceleration of the body must be zero.
Example of Uniform Motion:
• If the speed of a car is 10 m/s, it means
that the car covers 10 meters in one
second. The speed is constant every
second.
• Movement of blades of a ceiling fan.

11. Types of Motion
Non Uniform Motion:
• This type of motion is defined as the
motion of an object in which the object
travels with varied speed and it does not
cover same distance in equal time
intervals, irrespective of the time interval
duration.
11

12. Types of Motion
If a body is involved in rectilinear motion,
and if the motion is not consistent, then the
acceleration of the body must be non-zero.
Example of Non Uniform Motion:
• If a car covers 10 meters in first two
seconds, and 15 meters in next two
seconds.
• The motion of a train.

14. Categories of Motion
• Translational – It is the type, where an object
moves along a path in any of the three
dimensions.
• Rotational – It is the type, where an object
moves along a circular path about a fixed axis.
• Linear – It is a type of translational motion
where the body moves in a single direction
along a single dimension.

15. Categories of Motion
• Periodic – It is the type of motion that repeats
itself after certain intervals of time
• Simple Harmonic – It is the type of motion like
that of a simple pendulum where a restoring
force acts in the direction opposite to the
direction of motion of the object.
• Projectile – It is the type of motion which has
a horizontal displacement as well as vertical
displacement.

17. Conclusion
 Motion strengthens your muscles to better
support your body. It also provides movement to
your joints and strengthens your bones.
 In addition, motion provides a release of
hormones that makes you feel good, so it
positively affects your mental health.
