Projection Motion Simulator Worksheet
Name______________________________
Go to the projectile motion simulator at http://phet.colorado.edu/sims/projectilemotion/projectile-motion.swf
Derive a model which will predict the range of an object fired at an angle of 20 degrees.
Use your model to predict the range for these initial velocities:
Initial velocity
Range
14 m/s
18 m/s
22 m/s
26 m/s
Using the program, fire the tankshell at 20 degrees with the initial velocities above and record
the measured ranges from the program. (tape measure is on the bottom of the screen, be sure to
keep it on the x – axis to measure the range)
Initial velocity
Range
14 m/s
18 m/s
22 m/s
26 m/s
Calculate the accuracy and precision of this experiment.
Create an experiment to test how mass affects projectile motion.
Record the results of your experiment here. Does mass affect projectile motion? Why or why
not?
