Forces can change the size, shape, motion, and direction of objects. Applying force can crush, tear, or reshape objects. Pushing with increasing force on a stationary ball will make it start moving and move faster. Applying a force in the opposite direction can slow or stop a moving object. Blocking a moving basketball changes its direction. Experiments show applying more force makes objects travel farther when pushed.

Effects of Force when Applied to an Object
I. Learning Competency with Code
Explain the effects of force when applied to an object (S4FE-llla-1)
II. Background Information for Learners
What is a Force?
Your everyday life involves numerous task such as cleaning
the house, washing the dishes or playing. All these activities
include several movements that need you to push or pull objects
that may react differently. These activities can set objects in
motion, shift its direction, change its shape or put an object back
into a resting position. The movement of push and pull applied is
called force.
Force can change the size and shape of an object
An object may change its size and shape when force is applied
on it. A paper may change its size and shape when you tear, cut,
or even crumple it. When you accidentally drop the flowerpot made
of clay while you are transferring your plants, it may also change
its size and shape. There are so many ways that you can do to
change the size and shape of certain object. Some ways include
pushing, compressing, bending, stretching, chopping, and
squeezing.
Force can make a stationary object move or make moving
objects move faster
A stationary ball on the floor will move by giving it a small
push through kicking it. You can make it move faster by applying
a push in the direction to where it is moving. Therefore, a force can
make a stationary object move, and it can also make a moving
object move faster.
Force can slow down or completely stop a moving object
A stationary ball on the floor can be made to stop by applying
a force. In order to stop or slow down a moving body, there is a

4. need to apply a force in a direction opposite to the direction of
motion of the moving body.
Force can change the direction of moving object
In a basketball game, the players can change the direction
of the ball by blocking it. With these examples, force changes the
direction of a moving object.
The player uses force to make the
ball move.
The player is blocking the ball to
stop any pass or shoot made by
the other player.
The girl is applying force by
pushing the grocery cart to make it
move.

7. ACTIVITY 2. “How does force affect the movement of an
object?”
Directions: Perform the activity by following the given steps
below. Ask the help of your parents or adult family members
while doing the activity.
Record your observations in the data table below.
Activity Title: Push and Go
Materials: meter stick/ruler/tape measure, any available
material at home.
Procedures:
1. Look for a toy car, ball, book, plastic chair/table, and
trolley bag.
2. Choose only 1 material and place it on flat surface of the
floor.
3. Mark a starting point on the floor. Gently push the
material with your hand.
Observe how far it moved. Measure the distance that it
travelled using a
meter stick or ruler or tape measure.
4.Using the same material, repeat step 3, but this time,
push
the material with a stronger force. Observe how far it
travelled. Measure the
distance it covered in meters.
5. Repeat step 3 using the sane material, this time push it
with the strongest force.
6. Record your observation in the data table

Guide Questions:
1. How do you compare the distance travelled by the object
when you pushed it with a weak/gentle, strong and
strongest?
2. Which amount of force applied made the materials travelled
the farthest from the starting point. Nearest the starting
point?
3. What factors do you think affected the movement of the
materials?
ACTIVITY 3. Explain what change takes place when the
following actions are done.
1. cutting of trees
2. Pounding of garlic
3. slicing a cake
4. tearing a piece of paper
5. pushing a grocery cart
ACTIVITY 4. Study the picture below.
1. Explain what will happen to the can when hammered
