
Reading materials, video tutorials and drills on getting resultant vector using component method.
2. For Students with Fairly Sufficient Level on Prerequisite Content-knowledge and/or Skill(s):
 Conduct short discussion or drills on the areas that the student finds difficult
Introduction:
This part must articulate the following:
1. Time frame a student is expected to finish in learning the lesson (and where to contact the teacher when concerns arise)
a. The lesson will approximately run for 60 mins and if the need arises the teacher can be reached through the e-mail (ajturingan.official@gmail.com) or using the contact number
09453843947
2. The knowledge (RUA) the student is expected to gain from learning the topic/lesson
a. The learners will learn to calculate dot or scalar product of vectors
3. Context where the student is going to apply his/learning (In what PAA/EFAA and personal use?)
a. The learners can use the dot product of two vectors to solve real-life problems involving two vector quantities. For instance, learners can use the dot product to find the force necessary
to keep a sport utility vehicle from rolling down a hill
4. Overview of the Lesson
In this lesson, the students will learn about unit vector, its meaning, and when to use it to solve or address a problem. The learners will also be equipped to calculate for scalar product or dot product. Also,
students will learn to solve for resultant vectors and getting the angle of vectors.

Student’s Experiential Learning:
Chunk 1: Unit Vector
Formative question: What is a unit vector?
Chunk 2: Dot Product
Formative question: How do we calculate for scalar products?
Synthesis: Learners will understand that:


A unit vector is a vector that has a magnitude of 1, with no units. Its only purpose is to point – that is, to describe a direction in space
In calculating dot or scalar product, we calculate for the product of magnitudes of two vectors and the cosine of the difference of their angles.
RUA of a Student’s Learning:
Answer the following questions:
1. What is a unit vector?
2. Find the x and y components of vector A, given A = 5i – 6.3j

Post-lesson Remediation Activity:

The teacher will provide feedback on the outputs submitted by the students and conduct a tutorial session as the need arises. Then, give another similar activity to capture or achieve the
target competencies of the lesson.
