inertia").

IMPULSE
is a quantity that describes the effect of a net
force acting on an object (a kind of "moving
force").
11. 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
damages/injuriesby citing real lifesituations.
Learning Objective
12. Let's assume there's a car speeding toward
you, out of control without its brakes, at a
speed of 27m/s(60 mph).Can you stop it by
standing in front of it and holding out your
hand?
13. Unless you're Superman, you probably don't want to
trystoppinga movingcar byholdingout your hand.
It'stoobig,andit'smovingwaytoofast.
15. Thingsweneed toconsider in defining
momentum
The
object
hasa
mass
The
object
is
moving
Any moving object with aquantity of
matter hasmomentum.
16. Where:
p is the momentum in kilogram meter per second (kg.m/s)
m isthemassof themoving 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
17. What isthemomentum of a22-kg cart
which travelsat 1
.2m/s?
Given:
mass(m)-22kg
velocity (v)-1.2
m/s momentum
(p)-?
Formula:
18. What isthemomentum of a22-kg cart
which travelsat 1
.2m/s?
Solution: p =mv
p =(22kg)(1.2m/s)
p =26.4kg .m/s
19. What is the momentum of an object that
isnot moving?
If any object of any massisnot moving,it has
zeromomentum sinceitsvelocity iszero.
20. What doyou think will happen to the
busafter ifit passesalonga curvy road?
a.It willslowdown
b.It willspeedup
c.Itsvelocitywillspeedup
21. How will you describe the velocity
ofthebus?
a.It increases
b.It decreases
c.It doesnot changeat all
22. What can you say
about themassof
thebus?
a.It increases
b.It decreases
c.It doesnot
changeat all
23. When the object slows down or
moves faster, its velocity
decreases or increases. If there
isa changein thevelocity or the
mass of an object, there is also a
change in momentum. And that
change in momentum is called
IMPULSE.
24. Impulse=changein momentum
Forceisneeded tochangethe
momentum of thebody.
Thisforce(F)multiplied by thetimeof
contact (t)isknown asIMPULSE(I).(I =Ft)
I =Ft =mv
I =P
(p =mv)
TheSI unit for momentum (p)and impulse(I)is
newton-second (Ns)or kilogram-meter per
second (kg .m/s)
Bodieschangetheir momentum through
collisions.
25. SampleProblem 2:
An offensive player passesafootball of mass
0.42kg with avelocity of 25.0 m/sduesouth.If
the player is in contact with the ball for 0.050
s,what isthemagnitudeof theaverageforce
heexerts?
Given: Formula:
Ft =mv
mass(m)-0.42kg
velocity (v)-25.0 m/s,south
time(t)-0.050 s
force(F)-?
29. What doyou think istheimpulseofan
object movingwith constant momentum?
constant -nochange
There is no impulse or zero impulse for
objectsmovingwith constant momentum.
30. Any moving object hasmomentum
p =mv
Impulseisthechangein
momentum of amoving object.
I =Ft =mv
33. Answer thefollowingquestions:
1.What did you observe on the
massof thecueball beforeand
after collision? How about ball
#1?
Thereisnochangeinmass.
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
34. Answerthe followingquestions:
4. Is there a change in momentum
ofthecueballandball#1
?Why?
Y
esbecause there isa change in the
velocityofthecueballandball#1
.
Since the cue ball and ball #1have a
change in velocity after collision,
then both balls have a change in
momentum.
In collision, an object that
experiences a greater change in
momentumhasa greater impulse
35. Therefore, this shows the
relationship between
momentum and impulse. A
change in momentum is
equaltoimpulse.
46. Part 3.Real-W
orldApplications
Research and describe one real-world
application where the understanding of
momentum and impulse is crucial. Explain
how these concepts are utilized in that
application.
