2. Content Standard Performance Standard
The learners demonstrate
understanding of uniformly
accelerated motion, motion
in two-dimensions using
projectile motion as
example, impulse and
momentum, and
conservation of linear
momentum.
Propose ways to enhance
sports related to projectile
motion.

3. Module 1: You will learn how to describe uniform motion mathematically. With forces
and motion, you will be able to apply Newton’s Laws of Motion to practical problems in
free-fall, projectile motion, and understand the concepts of impulse and momentum. With
these, you will find out how ideas in Physics can help you play better in your favorite sports
Module 2: We will tackle work, power, and energy and explain how they are related to one
another. You will learn how conservation of energy can be used to describe the motion of man-
made objects like roller coasters, and the rush of water in waterfalls.
Module 3: You will encounter topics in heat and work and how these two relate with each
other.With the basic concepts on heat and work, you will understand how energy is transformed.
You will understand how heat is converted to work, and work to heat.
Module 4: You will learn how electrical energy is generated and transmitted. You will further develop your
understanding of the transmission of electricity from power stations of your homes. From these concepts, you will be
able to gain further insights on the transformation of energy that takes place in hydroelectric power plants.

5. “PASSWORD”
60-second game
How to Play:
1. Divide the class into two teams and put a chair
Infront of the whiteboard facing the class.
2. Write a word on the board
3. One person from one of the teams sits in the chair
and that person’s team tries to explain the word on
the board without saying a word.
If the person in the chair says the word, the team get
a point.

Units of Speed andVelocity is the same as

meters/second or m/s

18. EXAMPLE #1: You ran and made two laps around
a 400 m track. What were your average speed
and average velocity if you ran for 200 seconds?
Total distance you travelled is equal to 2x400m = 800 m
Displacement = Om
