Performance Task 6.1
ACCELERATION DUE TO GRAVITY
I. Objective: Explain the relationship between speed and acceleration
II. Materials: identical coins 2 pcs, table
III. Procedure:
1. Label the coins A and B.
2. Place coin A at the edge of a smooth table top so that it hangs over
slightly.
3. Place a coin B on the same table top some distance from the
overhanging coin A.
4. Slide the coin B across the table (such as by flicking with your finger)
so that it strikes the overhanging coin A and both coins fall to the floor
below.
5. Repeat Steps 2-4 but this time flick coin B harder so that it will have
greater speed as it strikes coin A.

speed in hitting coin B
VII. Observations and Discussions:

I observe that they hit at the same time even though
one coin hast to travel the farther distance to get his target
well it’s because the horizontal and vertical motions are
independent of each other. The objects fall at the same rate
because they are both influence by the acceleration due to
the gravity and because they fall at the same rate and the
horizontal motion has no influence this means that since they
fall the same distance they must take the same amount of
time.
VIII. Conclusion

I conclude that at any instant of time projected penny has
a downward velocity component like this and this is due to
gravity now the drop penny has also the same velocity vector
at the same instant of time, however the projected penny
also has a horizontal velocity component due to the flip that I
give it initially. The overall velocity vector the protected penny
is therefore diagonal to the two components and has a
magnitude that is greater than either of the components so
the average velocity of the projected penny is greater than
that of the drop penny with a greater average velocity the
projected penny will obviously travel a greater distance in the
same amount of time than the drop penny will.
IX. Guide Question:
Does landing of both coins on the floor depend on the speed of the sliding coin?
Explain.

Yes, it is. Landing of both coins on the floor depend on
the speed of the sliding coin because if you don’t give
enough force to flick the coin to the sliding coin, it won’t
land at the same time.
What I Have Learned
Activity No. 6.1.2 Now I Know
Based on the lesson on the concepts of motion, I have realized that we can
control motion by the use of different forces. Force can make the object move and
it can make the object stops. It can also change the direction of motion.

projectile motion is similar and different from Galileo through a Venn diagram. 1

notebook, coin
III. Drawing of the Set-up:

simultaneously. Which falls to the ground faster?
Record at table 6D
3. Hold the piece of paper and the notebook at the same height. Drop them
simultaneously. Which falls to the ground faster? Paper or notebook?

I observed that if an object is heavier like, crumbled

paper, notebook and a coin than a piece of paper is going
to hit the ground first.
VIII. Conclusion:
I conclude that if an object that fall faster or hits the

ground first it’s because it has a small surface area thus
comes in contact with fewer air molecules and is subject to
less air resistance.
IX. Guide Question:
What factors the fall of the object? Justify your answer.
 Gravity the higher the force of gravity, the higher the
acceleration of the object, independent of its mass.
 Its mass
 Its surface area
What I Have Learned
Activity No. 6.2.2 Motion CERA-Context, Experience, Reaction, Application
Based on the lesson on uniform acceleration, I have realized that uniform or
constant acceleration is a type of motion in which the velocity of an object
changes by an equal amount in every equal time period. The motion of a freely
falling body and a vertically thrown up body are the example of uniform
acceleration.
What I Can Do
Activity 6.2.3 Caption Time
Place your detailed caption below the image to infer Galileo’s explanation on
motion concepts: objects in vacuum fall with uniform acceleration and force was not
necessary to sustain horizontal motion

Performance Task 3.3
INERTIA IN MOTION
I. Objective: Explain Newton’s First Law of Motion
II. Materials: ball, clearly-marked target (i.e., notebook paper, tape or pal), tape
measure or ruler
III. Procedure:
1.
Mark the starting line A and place a target about 10 meters away from it
(C). Mark B about 1m (3.28 ft) before the target and mark D 1 m after
the target.
2. With the ball on your hand, you are about to sprint towards the target
respectively and with a goal to drop the ball on the target. Record your
predictions on table 6D.
3. Hold the ball and do not let your elbow leave your side as you sprint
toward the target and drop the ball. Do not give the ball an initial velocity;
hold the ball from its sides so that you can release freely your grip as you
let it drop.
4. Record where the runner released the ball and where the ball strikes the
ground.
5. Draw the best diagram for each attempt to drop the ball on the target.
Specify where the ball was released and where it actually landed.
6. Repeat the experiment until the ball hits the target.
7. Repeat 2 but this time, do not sprint just run in a slower speed.
8. Repeat 2 but in a walking speed.

IX. Question:
How will you relate today’s activity with Newton's First Law of Motion and
with inertia?
What I Have Learned
Activity 3.3.2 Looking Back
Now that you are done knowing motion and force concepts, take a look back and
remember the things you learned.
Based on the lesson on inertia, I have realized that Inertia resists
change in motion. Objects want to stay in rest or motion unless an outside force
causes a change. For example, if you roll a ball, it will continue rolling unless
friction or something else stops it by force.
What I Can Do
Activity 6.3.4 Friction Imperfection
Consider an old book that slides on a table and eventually comes to a halt.
Differentiate Galileo and Newton’s concept on why a moving it tends to go to a
rest position. 1 point each

Questions
1.What forces are acting
on the book?
2. What is the direction
of the forces?
3. Compare the
magnitude of the force.
4. Are the forces
balanced or unbalanced?
Balance
Unbalanced
5. When does an object
comes to its rest
position?
An object at rest stays
at rest and an object in
motion stays in motion
at a constant speed and
direction unless acted
upon by an unbalanced
force.
That
moving objects eventually
stop because of a force
called friction.
