Introduction:

For this Laboratory, we are going to use the Phet Interactive Laboratory to determine the effects of initial velocity, angle and mass to the maximum height, time of flight and range of a projectile.

Procedure I (Varying Projectile Mass):

1)    On your browser, type the following url:

 https://phet.colorado.edu/sims/html/projectile-motion/latest/projectile-motion_en.html

2)    After the page loads, select the Lab option that shows on your computer screen. This should bring you to the screen as you see in Figure 1.

3)    Set the angle of the cannon at 60 degrees with respect to the horizontal.

4)    Set the initial velocity of the cannon at 5 m/s.

5)    On the table located on the upper right hand corner of the screen, select different cannon mass values as shown on table 1.

6)    Determine the total time of flight, height and range of the cannon projectile using the floating table located at the top of the screen.

7)    Fill out all of the blank boxes on Table 1.
