Activity 4 - Projectile and Air Resistance (Activity Guide)
I. Introduction
III. Procedure
1. Go to https://phet.colorado.edu to access the Phet Simulations. In the home page,
search for Physics Simulation on Projectile Motion.
2. Practice on how to use the simulation. You may explore the attributes of the
simulation before proceeeding with the exercises.
3. Each exercise includes a different set of attributes for your simulation. So make
sure to set the correct values. Asnwer the questions BASED on the Phet Simulation.
4. Input your answers in the DATA SHEET provided for you. DO NOT write
answers in the this Activity Guide.
5. Do not forget to include screenshots of the simulations in your lab report.

Exercise A.
For this part, use the Drag simulation, as shown in the screenshot.

A. Assume a drag coefficient of 0, 1, 2 and 3 with the same initial velocity (V0x) of
+18m/s, height y = - 10m and a diameter of 0.1m. Complete Table 1 by finding the
displacement (x) of the cannonball in each of the given components or attributes of
the motion.
Exercise B.
Using the same simulation as in Exercise A, assume a constant drag coefficient of 5,
constant velocity of +18m/s, constant height of y=- 10m and diameters 0.1m, 0.3m
and 0.5m. Complete Table 2 by finding the displacement(x) of the cannonball in each
of the given attributes of motion.
Exercise C.
For this exercise, use the Lab simulation described in the figure.

C1.Assume no air resistance (drag coefficient = 0). Complete Table 3 of the Data
Sheet by determining the value of the displacement for the given angle of incidence
C2. Assume no air resistance (drag coefficient = 0). Complete Table 4 of the Data
Sheet by determining the value of the range x for the given increasing initial speeds.
