7. Let’s
Think!
Imagine that you are
running very fast
when suddenly,
someone blocks your
path. What do you
think will happen?

8. Melcs: Relate impulse and momentum to the collision
of objects (e.g., vehicular collision) (9FE-IVb-36)

9. LEARNING
TARGETS:
 Define momentum.
 Describe how mass and
velocity affects the
momentum of the object.
 Calculate the momentum of
the moving objects.
 Deduce road safety
practices.

10. Let’s
Explore
Group Activities:
1. Crash Course Momentum
(Story Reading)
2. Rolling Marble Activity (for
velocity)
3. Rolling Marble Activity (for
mass)
4. Bouncing Ball Activity
5. Car vs Truck (video watching)

12. Momentum
“Mass in motion”
The object has momentum
if:
• It has a mass
• It is moving

13. Mathematically, it is expressed as
𝑝 = 𝑚 𝑥 𝑣
p – is the momentum of the moving object
(kg●m/s)
m – is the mass of the moving object (kg)
v – velocity of the moving object (m/s)

14. Sample
Problem:
What is the momentum of 22
kg grocery cart which travels
at 1.2 m/s?
Solution:
p = m x v
p = 22 kg x 1.2 m/s
p = 26.4 kg●m/s

15. How does VELOCITY affect the momentum of a
moving object?
The momentum increases as
the velocity increases.

16. How does MASS affect the momentum of a
moving object?
The momentum increases as
the mass increases.

17. Does momentum of an object can be transferred
to another object?
Yes, the momentum
is transferred when
one object hits
another object. The
momentum moves
from one object to
another.

19. Let’s
Apply
A large truck and a car are
both moving at the same
speed. If both of them lose
their brakes and crash
against a wall, which would
suffer greater damage, the
truck or the car? Why?

20. Let’s
Apply
If you were in a car that
was out of control and
had to choose between
hitting a haystack or a
concrete wall, which
would you choose? Why?

21. Let’s
Apply
Cars used to be built as rigidly
as possible to withstand
crashes. Today, though, cars
are designed to have “crumple
zones” that collapse upon
impact. What is the advantage
of this new design?

22. Let’s
Evaluate
Answer the following problems.
a. A 5.0 kg ball is launched with a speed of 2.0 m/s. Find the momentum
of the ball. (1 point)
b. A 500 kg car is driving at a speed of 4 m/s. Find the momentum of the
car. (1 point)
c. Two students are running in a cross-country race. One has a mass of
60 kg, while the other has a mass of 70 kg. If they are both running at a
speed of 7 m/s, which has more momentum? Why?
(3 points)

23. Let’s Extend
Define Impulse and
how is it related to
momentum.
