I. OBJECTIVES Objectives must be met over the week and connected to curriculum standards. To meet the objectives, necessary procedures must be followed and if needed, additional lessons, exercises and remedial activities
may be done for developing content knowledge and competencies. These are assessed during Formative Assessment strategies. Valuing objectives support the learning of content and competencies and enable
children to find significance and joy in learning the lessons. Weekly objectives shall be derived from the curriculum guides.
A.Content Standards The learners demonstrate an understanding of:
 Newton’s three laws of motion and uniform circular motion
B.Performance Standards The learners should be able:
 Develop a written plan and implement a “Newton’s Olympics”
C.Learning Competencies/Objectives
Write the LC code for each
 Investigate the relationship between the amount of force applied and the mass of the object to the amount of change in the object’s
motion ;( S8FE-Ia-15)
 Infer that when a body exerts a force on another, an equal amount of force is exerted back on it; (S8FE-Ia-16)
 Demonstrate how a body responds to changes in motion; (S8FE-Ib-17)
OBJECTIVES:
1. Identify and recognize the different types of forces.
2. Familiarize with the three laws of motion: Law of Inertia, Law of Acceleration, and Law of Interaction
3. Perform activities related to the Newton’s Law of motion
4. Appreciate the importance of the application of Newton’s Law of motion in our daily encounter.
II. CONTENT Content is what the lesson is all about. It pertains to the subject matter that the teacher aims to teach. In the CG, the content can be tackled in a week or two.
FORCES AND NEWTON’S LAW OF MOTION
III. LEARNING RESOURCES List the materials to be used in different days. Varied sources of materials sustain children’s interest in the lesson and in learning. Ensure that there is a mix of
concrete and manipulative materials as well as paper-based materials. Hands-on learning promotes concept development.

IV. PROCEDURES These steps should be done across the week. Spread out the activities appropriately so that students will learn well. Always be guided by demonstration of learning by the students which you can infer from
formative assessment activities. Sustain learning systematically by providing students with multiple ways to learn things, practice their learning, question their learning processes and draw conclusions about
what they learned in relation to their life experiences and previous knowledge. Indicate the time allotment for each step.
A.Reviewing previous lesson or
presenting the new lesson
DAY 1
PRESENT the topics for FIRST QUARTER.
Then,
After learning about the ways by which the motion of an object can be described and represented in Grade 7, you will now study the motion
of objects using the concept of force. Let’s review your prior knowledge by answering the following questions.
1. What makes objects move the way they do?
2. Why do objects move in different ways?
3. Why are some objects faster than the others?
4. What makes objects stay in place?
B. Establishing a purpose for the
lesson
Get a ball or any round object. Place it on top of a table. Answer the following questions:
1. Will this object move by itself?
2. How can you make this object move?
3. While it is moving, how will you make the object speed up or slow down?
4. How can you make it stop?
5. How can you make it change its direction?
C.Presenting examples/instances of
the new lesson
Then discuss FORCES:
Balanced and Unbalanced Forces
Any object may be acted upon by several forces. Forces are described by the following terms: magnitude and direction. Magnitude
refers to the size or strength of the force. An arrow is used to indicate the direction of the force. The length of the arrow represents the
magnitude of the force.
The ball is at rest and placed on a table. You may notice that there are two forces acting on the object. The table is exerting an upward
force on the ball This is called the normal force. There is also a downward force acting on the object. This is the force of gravity. The object

remains at rest because the forces acting on the ball are equal in magnitude and in opposite direction and they lie on the same line of
action. The forces are said to be balanced. When the forces acting on an object are balanced, the object does not move.
Measure of Inertia
All objects have the tendency to resist changes in their state of motion or keep doing what they are doing. However, changing
a body’s state of motion depends on its inertia. A more massive object which has more inertia is more difficult to move from
rest, slow down, speed up, or change its direction.
Newton's first law states that an object at rest will stay at rest or an object in motion will stay in motion and travel in a
straight line, if no external net force acts on it. The object will change its state of motion only if there is unbalanced or net force
acting upon it.
D.Discussing new concepts and
practicing new skills #1
DAY 2
ACTIVITY 1: INVESTIGATING INERTIA
E. Discussing new concepts and
practicing new skills #2
DAY 3
Explain briefly the second law of motion: Newton’s Second Law and Third Law of Motion: Law of Acceleration and Law of
Interaction
If the net force acting on an object is constant, its velocity changes at a constant rate over time. Hence, it is moving with constant
acceleration. But if the force acting on the object is changed, its acceleration will also change. When the net force is doubled, acceleration
is also doubled. When it is tripled, acceleration is also tripled. We can therefore say that at constant mass, the acceleration of an object is
directly proportional to the magnitude of the unbalanced force F acting on it. This relationship can be mathematically expressed as:
a = kF where k = mass
What if the mass of the object is changed and the force is kept constant? Acceleration also varies with the mass of the object. As the mass
of the object increases, with the same amount of force applied, its acceleration decreases.
Then proceed to the activities to be done by group:
ACTIVITY 2: THE SECOND LAW OF MOTION
ACTIVITY 3: Action-Reaction (Paper Bullet)
F. Developing mastery DAY 4
Write T if the statement is TRUE and F if the statement if FALSE
1. Inertia is the tendency of an object to resist motion.
2. Newton’s first law of motion is also called the law of acceleration.
3. If an object is at rest, inertia will keep it at rest.
4. The tendency of an object to resist a change in motion depends on its mass.
5. The relationship between mass and inertia is described by Newton’s second law of motion.

6. Newton determined that there is a direct relationship between force and mass.
7. The greater the net force applied to a given object, the more it will accelerate.
G.Finding practical applications of
concepts and skills in daily living
 When a bowling ball strikes a bowling pin.
 A man is pulling a rope that is attached to a wall.
 While driving down the road, a bird suddenly strikes the windshield of a bus and fall on the ground. The bird hit the bus and the bus
hit the bird.
H.Making generalizations and
abstractions about the lesson  Newton’s first law of motion states that a body will remain at rest or move at constant velocity unless acted upon
by an external net or unbalanced force. It is also known as the law of inertia.
 Inertia is the tendency of an object to resist changes in state of motion or keep doing what they are doing. The
more massive an object is, the more inertia it has.
 Newton’s second law of motion states that the acceleration of an object is directly proportional to the magnitude of
the net force acting on it and is inversely proportional to its mass.
 The difference between the forces related to Law of Interaction and forces in a balanced state are as follows:
Action Forces Reaction Forces
 Two forces are equal in size.
 Two forces are opposite to each other in
terms of direction.
 Two forces have the same line of action.
 Action acts on one object, while reaction
acts on another object.
 Two forces are equal in size.
 Two forces are opposite to each other in
terms of direction.
 Two forces act along the same line.
 Two forces act upon the same object.
