2. EXPLORE (Providestudents with different experience)
Group Activity:
1. Go to your group, assemble and stay in one place.
2. Introduce the activity/taskto the students.
A. Group 1 willwatch a video and answer the following questions.
1. A habal-habal motor bicyclefrom rest accelerates on a road at 5.5
m/s2 for 15 seconds until it passes aling Tinas bakery. What is the
distance coveredwhen the habal habal motor bicyclereaches Aling
Tinas bakery?
Given:
a = 5.5 m/s2
t = 15 s
vi = 0 m/s
d = ?
Equation:
d=Vit+1/2Ag t2
2. A rock is dropped on the 3rd flood of the school building and hits the
ground after 2.6 seconds, what is the height of the building? And
what is the final velocity?
Given:
a = -9.8 m/s2
t = 2.6 s
vi = 0 m/s
d = ?
vf = ?
Equation:
1. d=Vit+1/2Ag t2
2. vf = vi + a t
-Leader of the group will
designate each members
for task:
-assigned member of the
group willcollectthe
materials needed forthe
activity fromthe
teacher.
-Groups will perform the
activity.
Solution:
d=Vit+ ½ a t2
d = (0 m/s)(15s) + ½ (5.5 m/s2
)(15s)2
d = ½ (5.5 m/s2
)(225 s2
)
d = ½ (1,237.5 m)
d = 618.75 m or 619 m
Solution:
d=Vit+ ½ a t2
d = (0 m/s)(2.6s) + ½ (-9m.8m/s2
)(2.6s)2
d = ½ (-9.8 m/s2
)(6.76m2
/s2
)
d = ½ (-66.25 m)
d = -33.12 m or -33 m
vf = vi + a t
vf = 0 m/s+ (-9.8 m/s2
)( 2.6 s)
vf = 0 m/s+ -25.48 m/s
vf = -25.48 m/s

Teacher’s Input: Generalization
 (Students and teacher interaction) discussion on the subject matter.
 Base on our what we have done, what do think our topic is?
Motion “Uniformly Accelerated Motion (UAM)” verticaland
Horizontal.
Generalization:
 Teacher ask question on:
1. What does UAMstands for?
(Uniformly Accelerated Motion). What does it means?
Is a motion having a constant acceleration.
Itmeans that an objectthat is moving is having a continuous
change in velocity every second.
2. How will you calculatedx? How about dy? What are the equations
used in UAM?
Answer: we uses kinematic equations.
For:
dx: weused (d= vi t + ½ a t2)
dy: wealso used (d= vi t + ½ a t2)
3. what’s the difference in the using this equation horizontally and in
vertically?
Answer: for Horizontal, the acceleration varies, while for
Vertical the acceleration used is constant which is -9.8 m/s2.
For vertical,the velocity changes 9.8 m/s.
In the activity,youjust used different equations to solve the problem
given to you. And these are kinematic equations or Motion equations.
4. What do negative sign indicate?
Answer: the objectis moving down, the moving leftside or
decelerating.
Application:
Teacher ask the followingquestions:
1. Why is this subject matter important?
Possible Answer: Solveproblem regarding motion. Since most of the
things in this world move weuse this to study motion by using kinematic
equations. And also identifying the distance of the height of the building.
- students Answer may
vary.(Uniformly
Accelerated Motion).
- May share additional
information regarding
the topic of discussion.
-Student will answer the
given question.
-Student will answer the
given question.
Answer: for Horizontal
the acceleration varies
while forVertical the
acceleration used is
constant which is -9.8
m/s2.
Answer: the (-)negative
sign indicates the
direction of the moving
object.

6. 2. Where do you think this topic can be useful?
Possible Answer: calculating the speed or velocities and acceleration of
the moving objectslike: cars, jeeps, and motor cycle.
3. What other ways can we apply this in our daily life?
Answer:
a. mechanical machines: motor engines
