The document outlines a lesson plan focused on teaching students about forces, including their definitions and effects on motion. It includes learning objectives, types of forces (contact and non-contact), activities for demonstrating force concepts, and evaluation methods to measure understanding. By the end of the lesson, students are expected to define a force, explain its effects, and recognize its role in everyday situations.

FORCES
Forces that are equal in strength and
opposite in direction, resulting in no net
force on an object.
Forces that act on an object without
physical contact, such as gravity or
magnetism.
Forces that act on an object through direct
physical contact, such as friction or normal
force.
FORCE
A push or pull that can cause an object to
change its speed, direction, or shape.

7. A force is a push or pull
that can cause an object
to:
 Change its speed
 Change its direction
 Change its shape
Introduction to Forces
C. Developing and Deepening Understanding

8.  Forces are interactions between
objects that can make objects
move, stop moving, or change
the way they are moving.
 Forces can be contact forces,
where objects touch, or non-
contact forces, where objects
don't need to be in direct
contact.
Introduction to Forces
C. Developing and Deepening Understanding

9. Contact Forces
 These are forces that require
direct physical contact
between objects.
Non-Contact Forces
 These are forces that can act
on objects without them being
in direct physical contact.
Types of Forces
C. Developing and Deepening Understanding

10. Contact Forces
Examples include:
 Friction - the force that
opposes the motion
between two surfaces in
contact.
Types of Forces
C. Developing and Deepening Understanding

11. Contact Forces
Examples include:
 Tension - the force
transmitted through a
string, rope, or cable
when it is pulled tight
Types of Forces
C. Developing and Deepening Understanding

12. Contact Forces
Examples include:
 Normal force - the force
exerted perpendicular to
the surface when one
object pushes against
another.
Types of Forces
C. Developing and Deepening Understanding

13. Contact Forces
Examples include:
 Muscular force is the force
exerted by the muscles when
they contract or shorten.
 It is the force that allows us to
move our body parts and
interact with the external
environment.
Types of Forces
C. Developing and Deepening Understanding

14. Non-Contact Forces
Examples include:
 Gravity - the force that attracts objects with
mass towards each other.
 Gravitational force is responsible for bringing
the items we toss into the air back to earth.
When an object is resting on a surface it is
exerting a downward force equal to its weight,
and this downward force is known as
Gravitational force.
Types of Forces
C. Developing and Deepening Understanding

15. Non-Contact Forces
Examples include:
 Electrostatic Force- The
electrostatic force is very similar to
the gravitational force. The
difference here is that gravitational
force acts between masses and
an electrostatic force acts
between two charged bodies.
Types of Forces
C. Developing and Deepening Understanding

16. Direction
 Forces have a specific direction in
which they act, either pushing or
pulling an object. The direction of a
force can change the object's motion.
Magnitude
 The magnitude of a force refers to its
strength or size.
 The greater the magnitude of a force,
the greater its effect on an object.
Force Characteristics
C. Developing and Deepening Understanding

17. Objects Involved
 Forces always involve at least two
objects - the object exerting the
force and the object experiencing
the force.
 The properties of these objects,
such as their mass, surface area,
and texture, can affect the force.
Force Characteristics
C. Developing and Deepening Understanding

18. The force of friction acts in the opposite direction
of an object's motion.

surface supporting an object.

object is proportional to their masses.

22. LESSON ACTIVITY
Activity 1. What Forces Can Do
Objectives: At the end of the demonstration, the student
should be able to describe what a force is and its effect on
objects.

 rubber band
 toy car
C. Developing and Deepening Understanding

23. LESSON ACTIVITY
Activity 1. What Forces Can Do
Procedures:
1. Allow the students to describe the size and shape of the soft
rubber ball. Push the rubber ball against a wall or a table. Ask
them to observe and explain what happened to the ball. Pull the
opposite ends of the rubber band and let them compare and
contrast their observations.
Guide them to answer the following questions:
a. What happened to the ball when you pushed it against a wall or
table?
b. What is applied in the two instances?

Procedures:
2. Place the toy car on the table or the floor. Ask the students how
to make the toy car move.
3. Push the toy car. Let the students describe the motion of the toy
car. Ask them how to make the toy car move faster, slower, stop, or
even change direction. Let volunteer students demonstrate what
they think will be able to change the state of motion of the car.

Procedures:
4. Ask the students to summarize their learning through recitation
or
sharing. Highlight that the activities demonstrated what a force can
do or the effect of forces on objects:
● A force can change the size and shape of an object.
● A force can make a stationary object move.
● A force can speed up, slow down, or stop a moving object.
● A force can change the direction of a moving object.

26. LESSON ACTIVITY
Activity 1. What Forces Can Do
Procedures:
5. Ask the students to describe a force and its effect on objects
using their own words.
6. Examples of real-life situations where forces are applied can be
given to students to allow them to identify the effects of these
forces. For example, pushing a cart, kicking a soccer ball, modeling
a lump of clay, the strong wind that moves a sailboat, or kicking
hard an empty can used in a game of Tumbang Preso.
