3. One of the most common team sports is
basketball. Imagine two teams
who are involved in a really tight quarter
finals tournament. Team A is 2 pts ahead of
Team B. Later on in the match, a player from
Team B scores a threepoint shot and followed
by a series of 2-point shots from the said
team. Team
B couldn’t stop their momentum.
4. MOMENTUM
the object has mass
the object is moving
any object with quantity of matter has
momentum.
“mass of motion”
equal to the product of mass and
velocity.
5. 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)
6. Given the information above, what is now the
momentum of an object that is not moving?

7. Given the information above, what is now 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 zero.
8. Suppose you ride a bus from Iligan City to
Cagayan de Oro City. What do you think will
happen to the bus after if it passes along a
curvy road?
a. The bus will slow down.
b. The bus will speed up or move faster.
c. The velocity of the bus will not change.
9. After passing a curvy road, the bus
travels in a straight road. How will
you describe the velocity of the bus?
a. it increases
b. it decreases
c. it does not change at all
10. There were only 25 passengers in the bus. Along
the way, 5 passengers drop at Laguindingan bus
stop, and another 4 passengers dropped-off at
Opol bus stop. What can you say about the mass
of the bus?
a. it increases
b. it decreases
c. it does not change at all
11. ----when the object slows down, its velocity
decreases
-----when the object moves faster, its velocity
increases
If there is a change in the velocity or the mass of
an object, there is also a change in momentum.
12. That change of momentum is called Impulse.
Impulse = Change in Momentum
Constant means there is no change.
Therefore, there is no impulse or
zero impulse for objects moving with constant
momentum.
13.
14. Collision of objects is one of the most common
situations where impulse and
momentum exists. Collision happens when objects
bump each other resulting in an exchange
of impulse and momentum.
total momentum before collision = total
momentum after collision
ptotal before collision = ptotal after collision
m1v1 + m2v2 = m1v1’ + m2v2

17. Suppose a car (the one pictured below) is travelling along a
concrete road (A),
curvy road (B), rough road (C) and cemented road (D).
1. At point A, the car increases its velocity. Then, there is a
change in the momentum of the car.
2. At point B, the car should increase its velocity and to have
less momentum.
3. There is no impulse when driving along point C.
4. If the car has constant velocity along point D and beyond,
the car’s impulse is zero.
18. Modified True or False. Write true on the space provided
before the number if the statement is correct, but if it is false,
change the underlinedword or group of words to make the
whole statement true.
___________1. A moving object has momentum.
___________2. When the object slows down, the velocity
increases.
___________3. An object with zero velocity has zero
momentum.
___________4. An object moving with constant momentum
has impulse.
___________5. If there is no change in momentum, there
would be no impulse
