The learners will be group into four to do the learning task.
Learning Task 2
An Investigation of Projectile Motion
Direction: In this activity, you will be acting as an artillery sergeant for
the United Philippine Army. Your commanding officer has assigned you
the task of identifying and explaining the factors that affect artillery fire.
These factors include the object being fired, angle of fire, and the initial
velocity of the fired object. In this activity, you will use a computer
simulation to investigate the variables of projectile motion.
Objective: Investigate the launch angle, initial velocity, and size &
shape of a projectile in order to explain how these variables affect the
projectile’s motion.
Materials: computer/cellphone, manila paper, marker
Procedures:
1. What do you think? Think about a ball flying through the air, a
cannon ball fired from a cannon, or any form of projectile motion.
There are many possible things that affect the trajectory (motion)
of the projectile. The most important of these factors are the
angle, the initial velocity, and the size & shape of the object
being fired. Think about each variable and describe how it may
affect a projectile in motion.
2. Now Experiment and Record Observations. Go to the PHET
website http://phet.colorado.edu, click on “Simulations,” scroll
down, and select the “Projectile Motion” simulation. You will
investigate how the three variables from part a) affect projectile
motion. You want to focus particularly on the maximum height
and maximum range of the projectile.
NOTE: Set the following parameters. These parameters will be
known as the “DEFAULT PARAMETERS.”
Object
= “tankshell”
Angle (degrees)
= 80o
Initial Speed (m/s)
= 18 m/s
Altitude (m)
= 0m
Air Resistance should not be checked
All other parameters should be controlled by the simulation. DO
NOT change them!
Guide Questions:
1. How does the angle affect projectile motion? Change the
angle option to read 15o and then click fire, and observe the
resulting motion path. When it finishes, repeat the instructions,
but use angles of 30o, 45o, 60o, 75o. Determine the trend of the
data. That is, compare the motion paths of each angle, and
write your observations below.
2. How does initial velocity affect projectile motion? Reset the
parameters to DEFAULT conditions specified above and click
the “Erase” button (this should erase all your motion paths from
above). Now change the initial velocity to 15 m/s and click fire,
and observe the resulting motion path. When it finishes, repeat
the instructions, but use 18 m/s, 21 m/s, 24 m/s, 27 m/s, and 30
m/s.
Determine the trend of the data, and write your
observations below.
3. How does size & shape affect projectile motion? Reset the
parameters to DEFAULT conditions and click on the “Erase”
button. Now change the object to a baseball, click on fire, and
observe the motion path. Repeat the instructions for a bowling
ball, adult human, piano, and Buick. What do you notice about
the motion paths?
4. How does size & shape affect projectile motion? Reset the
parameters to default and click on the “Erase” button. Now
repeat part 3, but check the air resistance box. Observe the
motion paths and record your observations below. Be sure to
think about the size, shape, and weight of each object.
Generalization:
1. What is projectile?
Projectile is any object that has been launched/dropped or
thrown in a particular direction from one point
2. What is the two-dimensional path that a projectile follow?
The two-dimensional path that a projectile follow is called
trajectory.
3. The motion of the projectile is described in terms of its
position, velocity and acceleration, give some examples of
projectiles.
a. An arrow fired at an archery target
b. A golf ball hit off the tee
c. A stone kicked off the top of a cliff
d. A tennis ball served horizontally
e. A gun firing a shell
Integration: MAPEH
1. What are the different types of sports?
The different types of sports categories are:
 Individual Sports
 Partner Sports
 Team Sports
Team sports can then be broken down into four categories:
o Invasion Games
o Net Games
o Fielding & Striking Games
o Target Games
 Extreme Sports
4. What factors do you think affect projectile movement?
a. initial velocity, V0
b. angle of projection, θ
Integration: MATH
Complementary Angles - two angles whose sum is 90
degrees & when put together form a right angle.
c. point of release
d. gravity
Application:
5. How do you relate projectile motion to a particular sport?
Understanding projectile motion allows us to accurately
predict and analyze the trajectory, range, and impact of these
objects.

E. Engagement
D. Assimilation
What I have learned?
Direction: Choose the letter of the best answer. Write your answer in

a. horizontal velocity
b. projectile motion
c. parabola
d. directrix

b. Projectiles do not follow a predictable path.
c. a wavy line
d. a parabola
3. A bullet is fired into the air at an angle of 30° to the horizontal. At the
same time and from the same height, a bullet is dropped. If we
neglect the effects of air resistance, how will the time the two bullets
spend in the air compare?
a. there is not enough information to determine this
b. the bullet that is fired will spend less time in the air, hitting the
ground first.
c. the bullet that is fired will spend longer in the air, hitting the
ground after the dropped bullet.
d. both bullets will spend the same amount of time in the air, hitting at
the same time.
4. Which of the following is NOT an example of projectile motion?
a. a hot-air balloon drifting toward Earth
b. a volleyball served over a net
c. a long jumper in action
d. a baseball hit by a bat
5. Which of the following is an example of projectile motion?
a. a bullet being fired from a gun
b. a jet lifting off a runway
c. a space shuttle orbiting Earth
d. dropping an aluminum can into the recycling bin

Words to Live By…
"Life is like a projectile motion how much hard work you will do as
maximum velocity then it will have a maximum height as success."
- Vishal Kumar
The learners, in their notebook, journal or portfolio will write their
personal insights about the lesson by completing the statements below.
