2. Learning
Objective
At the end of the lesson, the learners are
expected to:
a.Define and identify the factors that affects
momentum and impulse;
b.Relate impulse and momentum to collision of
objects (e.g., vehicular collision) [S9FE - IVb -36]
and;
c.Appreciate the importance of understanding
the causes and effects of collision-related

11. Let's assume there's a car speeding toward
you, out of control without its brakes, at
a speed of 27 m/s (60 mph). Can you
stop it by standing in front of it and
holding out your hand?

12. Unless you're Superman, you probably don't want
to try stopping a moving car by holding out your
hand.
It's too big, and it's moving way too fast.

13. How about if you bumped to another
player bigger than you?

14. Things we need to
consider in defining
momentum
&
The
objec
t
has a
mass
The
object
is
moving
Any moving object with a quantity
of matter has momentum.

15. Where:
p is the momentum in kilogram meter per second
(kg.m/s) m is the mass of the moving object in kilogram
(kg)
v refers to velocity of the moving object in meter
per second (m/s)
Mathematically it
is expressed
as:
P= m x v

16. What is the momentum of a 22- kg
cart which travels at 1.2 m/s?
Given:
mass (m) - 22 kg
velocity (v) - 1.2
m/s momentum
(p) - ?
Formul

17. What is the momentum of a 22- kg
cart which travels at 1.2 m/s?
Solution:
p = mv p =
(22kg) (1.2m/s)
p = 26.4 kg . m/s

18. What is the momentum
of an object that is not
moving?
If any object of any mass is not moving, it
has zero momentum since its velocity is

19. What do you think will happen to the
bus after if it passes along a curvy
road?
a.It will slow down
b.It will speed up
c.Its velocity will speed up

20. How will you describe the
velocity of the bus?

21. What can you
say about the
mass of the
bus?
a.It increases
b.It decreases
c.It does not
change at

22. When the object slows down or
moves faster, its velocity
decreases or increases. If there
is a change in the velocity or
the mass of an object, there is
also a change in momentum.
And that change in
momentum is called IMPULSE.

23. Impulse = change in
momentum Force is needed
to change the
momentum of the body.
This force (F) multiplied by the time
of contact (t) is known as IMPULSE
(I). (I = Ft) I = Ft = mv
I = ΔP
(p = mv)
The SI unit for momentum (p) and impulse
(I) is newton-second (Ns)or kilogram-meter
per second (kg . m/s)
Bodies change their momentum
through collisions.

24. Sample Problem 2:
An offensive player passes a football of mass
0.42 kg with a velocity of 25.0 m/s due
south. If the player is in contact with the
ball for 0.050 s, what is the magnitude of
the average force
he exerts?
Given
:
Formul
a: Ft =
mv
mass (m) - 0.42 kg
velocity (v) - 25.0 m/s,
south time (t) - 0.050 s
force (F) - ?

25. The force of impact is
directly proportional to
the momentum of the
body and inversely
proportional to the time
of contact.

26. The impact force could be
decreased by extending the

27. It decreases the impact force by increasing
the time of contact.

28. What do you think is the impulse of
an object moving with constant
momentum? constant - no change
There is no impulse or zero impulse
for objects moving with constant
momentum.

29. Any moving object has
momentum
p = mv
Impulse is the change
in
momentum of a
moving object.

30. What will happen
to a moving
object if it
collides with
another object?

31. Scenario #1:
Suppose you
are playing
billiard. The cue
ball and ball
#1 are initially
at rest. Then
you use the tako
to hit ball #1.

32. Answer the following questions:
1.What did you observe on the
mass of the cue ball before
and after collision? How
about ball #1?
There is no change in mass.
2.Since it is initially at rest,
what are the initial velocities of
the balls?
Zero
3.After collision, is there a
change in velocity of the cue ball?
ball #1?
Yes

33. Answer the following questions:
4. Is there a change in
momentum of the cue ball and
ball #1? Why?
Yes because there is a change in
the velocity of the cue ball and
ball #1.
Since the cue ball and ball #1
have a change in velocity after
collision, then both balls have a
change in momentum.
In collision, an object that
experiences a greater change in

34. Therefore, this shows the
relationship
between momentum and
impulse. A change in
momentum is equal to
impulse.

36. Which of the two cars has the
greater change of
velocity?
Car

37. 2. Which car has the greater
change in momentum? Explain
your answer.
Car A, because it travels faster

38. 3. Which car has the greater
impulse?
Car A, because it has greater change
in momentum.
