3. Uniform MotionUniform Motion
If an object moves equal distance in If an object moves equal distance in
equal interval of time.equal interval of time.
SpeedSpeed: can not be speeding up or : can not be speeding up or
slowing down.slowing down.
Uniform = “Constant”Uniform = “Constant”
Ex :- If an object go to Delhi from Panipat Ex :- If an object go to Delhi from Panipat
on a traffic less road. It reaches there in on a traffic less road. It reaches there in
2 hours by moving with constant speed 2 hours by moving with constant speed
of 30 km/h. n this case object covers of 30 km/h. n this case object covers
equal distance in equal interval of time.equal distance in equal interval of time.

distance in equal interval of time distance in equal interval of time
•SpeedSpeed: speed varies.: speed varies.
•Non uniform =“variable”Non uniform =“variable”
•Ex:- if an object go to Panipat from Ex:- if an object go to Panipat from
Delhi. In first hour it is moving with a Delhi. In first hour it is moving with a
speed of 50 km/h and in second speed of 50 km/h and in second
hour their was to much traffic and it hour their was to much traffic and it
moves with a speed of 10km/h. In moves with a speed of 10km/h. In
this case object cover unequal this case object cover unequal
distance in equal interval of time. distance in equal interval of time.

6. SpeedSpeed
Rate of change of distance is called Rate of change of distance is called
speedspeed
Average speedAverage speed is ratio of total distance is ratio of total distance
and total time taken .and total time taken .
Speed = distance ÷ timeSpeed = distance ÷ time
Speed is a scalar quantity so it has only Speed is a scalar quantity so it has only
magnitude (a number and units) and magnitude (a number and units) and
does not include direction.does not include direction.
Instantaneous speedInstantaneous speed is the speed at a is the speed at a
specific instant in time. specific instant in time.

7. VelocityVelocity
 Rate of change of displacement is called Rate of change of displacement is called
velocity .velocity .
Velocity is a vector quantity.Velocity is a vector quantity.
Velocity has both magnitude and Velocity has both magnitude and
direction. direction.
Ex. 56 km/h West OR -9.8 m/s Ex. 56 km/h West OR -9.8 m/s

8. Constant and Average Constant and Average
VelocityVelocity
When an object travels at the same When an object travels at the same
speed and the same direction for a time speed and the same direction for a time
interval, it has interval, it has constant velocity.constant velocity.
Average velocity: Average velocity: the displacement of
an object divided by the time interval it
takes to travel the displacement.

9. Speed GraphSpeed Graph
Also called Distance-Time GraphAlso called Distance-Time Graph
Distance is on the “y” axis.Distance is on the “y” axis.
Time is on the “x” axis.Time is on the “x” axis.
The slope of the line (how steep The slope of the line (how steep
it is) is the speed.it is) is the speed.

15. Calculate the speed.Calculate the speed.
Speed = d/t or rise/runSpeed = d/t or rise/run
Speed = (5000 – 1000) ÷ (200 – 40)Speed = (5000 – 1000) ÷ (200 – 40)
Speed = 4000 m ÷ 160 sSpeed = 4000 m ÷ 160 s
Speed = 25m/sSpeed = 25m/s
(40, 1000)
(200, 5000)
