LAGUNA STATE POLYTECHNIC UNIVERSITY
SAN PABLO CITY CAMPUSDel Remedio, San Pablo City
I. OBJECTIVESAt the end of the lesson, the students should be able to:
a) Identify the units for speed, acceleration, time, final velocity, initial velocity, and distance.b) Differentiate kinematics equation.c) Measure the distance, acceleration and elapsed time intervals for a variety of objects.
II. SUBJECT MATTERa) TOPIC
1.Kinematics Speed and Velocity Scalar and Vector quantities Distance and Displacement Acceleration Kinematic equations
III.LEARNING ACTIVITIESa) PREPARATORY ACTIVITIES (DAILY ROUTINE)
PRAYERTEACHER STUDENTS
- Before we start, lets first have aprayer. Charis, please lead the prayer.
- Classmates, let us bow our head andfeel the presence of God. Lord, thank
you for this wonderful day. Thank you
for the classmates and teacher we have.Please guide us in our discussion;
please give us courage to understand the
lesson. Please guide our teacher in histeaching. Give him the knowledge and
strength to execute his lesson. Lord,
forgive us for all the sins we commitand please lead us to a place far away
from disgrace and near your divine
love.
- Amen.- Thank you Charis. You may take your
sit.
GREETINGSTEACHER STUDENTS
- Good morning class. - Good morning sir.REVIEW OF PAST LESSON
TEACHER STUDENTS
- In our previous lessons, we learned thatMechanics is a sub branch of classicalphysics. It is divided into three parts
which are? Anyone?
- Yes?-
Sir!
- Sir, it is divided into Kinematics,Dynamics, and Static.
- Very good! Whereas, Kinematicsfocuses on the motion of a bodywithout regards the cause of the motion
while Dynamics focuses on the way in
which force produce motion and Staticsdeals with the way in which forces

combine with each other so as to
produce equilibrium.
- Did you understand? - Yes sir!
b) MOTIVATIONTEACHER STUDENTS
- Now class I need two volunteers whowill be our model for our next topic.
- Anyone?- Okay, the first volunteer will start from
the back and 10 steps towards here infront. And the second volunteer will
start at the back and walk 10 steps to
your left then 10 steps from your left
again and 10 steps again to your left.Clear?
- Sir!
- Yes sir!c) DISCUSSION
TEACHER STUDENTS
- Ok class, what difference you seebetween them?
- Very good! You see the first volunteerrepresent how the speed works whilethe second represent velocity.
- Can someone differentiate the two?- Yes?
- Very good! Speed is defined how fastan object is moving. An object that is
not moving has no speed. Somethingmoving very fast would have high
speed and then it follows that a slow
moving object would have low speed.
Whereas Velocity is defined as therate at which an object changes its
position. Think about a driver of a car
that drives ahead of a mile and thenthe driver puts the car in reverse anddrives back of a mileeach time
going back and forth and each time
returning to the original startingposition. The movement of the car
would never change position and
therefore it would have zero velocity.
- Did you understand?
- Now, do you have any idea when youhear the words Scalar and Vectors?
- Okay, Scalar quantities are defined bymagnitude alone, while vector
quantities are defined by magnitude
along with a direction. So, speed isknown as a scalar quantity and
velocity is known as a vector
- Sir, the first volunteer just walktowards to front whiles the secondvolunteer roam around the room.
- Me sir!- Speed is how fast an object is moving
while the Velocity is the speed withdirection.
- Yes sir!
- None sir!

quantity.
- Get me?- Distance and displacement are two
basic concepts that can also be easily
misunderstood. Distance is a scalarquantity that is described by
magnitude, and displacement is avector quantity describing how much
an object moved; in other words, thechange in position.
- To understand this concept further,consider a man who walks 1 mile
north, 2 miles east, and 1 mile south
and 2 miles west. The man would have
walked 6 miles (distance) but hisdisplacement is 0 miles. In this
example, the 1 mile North and Southcancel each other out and the 2 milesEast and West also cancelled each
other out and the person returned to the
starting point.
- Did you get the point?- Lets move on to acceleration,
acceleration is another concept that you
will need to get a handle on. Many
people misunderstand the meaning ofacceleration. Some people think that itmeans that something or someone is
moving fast. However, you can have an
object or a person moving really-reallyfast and yet not accelerating. To be
accelerating, an object or person would
have to change its velocity.Acceleration is usually depicted by
units per time units; the ones that are
used most frequent would be m/s/s,
mi/hr/s, km/hr/s. Remember thatacceleration has a direction associated
with it and therefore is called a vector
quantity. The actual direction of the
acceleration vector is dependent onwhether the object is going faster or
going slower and whether the object is
traveling in the positive or negativedirection.
- Did you understand?- Now lets move on to the Kinematic
Equation. Here are the equation:

- Yes sir!
- Yes sir!

(Examples here)
- Any questions? - None sir!d) GENERALIZATION
TEACHER STUDENTS
- Did you understand the lesson? - Yes Sir!- Is kinematic equation clear to you? - Yes Sir!- In your own words define distance,
displacement and acceleration.
- Distance is a scalar quantity that isdescribed by magnitude, and
displacement is a vector quantitydescribing how much an object moved;
in other words, the change in position.
To be accelerating, an object or person
would have to change its velocity andis usually depicted by units per time
units; the ones that are used mostfrequent would be m/s/s, mi/hr/s,km/hr/s.
- Precisely! You understood the lessonvery well.
e) APPLICATIONTEACHER STUDENTS
- Now, I want you to apply what you hadlearned from the topic today. In your
seat answer the following.
- A car accelerated from rest at a constantrate of 5.0 m/s
2.
a. How fast was the car going after15seconds?
b. How far was it from its initialposition after 25seconds?
IV.EVALUATIONAnswer the following questions:
1. At a car toy race, the winner moved at an average velocity of 4.8m/s for 4.2min. determine thewinning toy cars displacement during this time interval.
V. ASSIGNMENTBring a toy car, tape, marker and timer for our activity tomorrow.
