2. An object is said to be in motion if
it changes its position with respect
to the surrondings with the
passage of time. Example –
Airoplane is flying
3. TYPES OF MOTION
Translational or linear motion
Rotational motion
Vibrational or oscillatory motion
Translational or linear motion
Rotational motion
Vibrational
or
oscillatory motion
4. What is uniform motion ?
A motion said to be a uniform motion if a body
covers equal distance in equal intervals of time
this is called uniform motion .
5. What is speed ?
The rate of change in distance with respect
to the time this is called speed.
6. What is velocity ?
• The rate of change in displacement with respect
to the time. This is called velocity.
7. WHAt is non-uniform motion ?
A body is said to be non-uniform motion if a body
travels unequal distance in equal intervals of time
this is called non – uniform motion .
8. What is distance ?
Distance is defined as the length of the actual path
followed by a body between the point between
which if move
9. What is displacement ?
Displacement on the other hand is defined
as the shorest distance between two points
10. What is acceleration ?
Acceleration is defined as the rate of change of velocity suppose ,
body has velocity ( v) time t and v at time t=c then acceleration is
given by a = v-u
-t
