Projectile Launch Videos ~ Project Name:
I
What are the main assumptions involved when you calculate the range
of a given projectile? Can you explain why a "real" launch range is
slightly different than that predicted? What factors affect its motion?
Some of the earliest records of scientific experiments on projectiles involved the ballistics of
spears and stones. Survival of the fittest would suggest that hunters and conquerors who
mastered the concepts involved were more successful.
Extensive data has been collected over the centuries to ensure predictable and repeatable
flight paths. Let's check the predictability and accuracy of a few homemade projectile
launchers

Using a pencil, answer the following questions. The lab is marked based on clarity of responses, completeness,
neatness, and accuracy. Do your best! Please ensure that any data measured (or recorded) includes the
appropriate number of significant digits (only one uncertain digit).
This activity is divided into three sections:
● Proficient – this first section explores only the basic “core” ideas involved in understanding.
Students must demonstrate a sound understand with all of their answers in this section BEFORE
attempting the next section.
● Expert – Your instructor will NOT review this section if the Core section above shows any
misconceptions. In this section students will make predictions and apply the concepts and ideas
learned above. For complete mastery it is expected that data collection and scientific procedures will
be as accurate as possible. All work shown should be clear with any units included. Answers should
be rounded off to the correct number of significant figures based on the data collected.
● Mastery – Once again, your instructor will only look at this section provided he/she is confident that
the above Mastery criteria has been met. In this section students will demonstrate a deeper
understanding of the concepts through error analysis, experimental design etc. Physics concepts from
other units already covered will often be required here.
