Collisions Lab 2D ~ Project Name:
: __ Inquiry Question 1
A collision simulation is a great way to study momentum.
i T,
Explosives experts rely on this technology. Can you determine
the necessary initial conditions to recreate a perfect implosion?
Demolishing a building with explosives is a lot more precise than most people think.
Explosive experts must have mastered the law of conservation of momentum and
energy to be able to do this safely and effectively. Simulations are a great way to
study how this all works.

Instructions
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:
e Core — 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.
e Mastery — 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.
® Ace— 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.
