The
“Science Friction” Project
The
goal of Science Friction is to help students understand
that Physics is all around us, even on the very ground
we walk on. Students will be creating a software program
for the theatre industry to calculate how sticky the
floors are in the movie theatres by modeling friction
to adhesion. Movie theatres, which are notorious for
having sticky floors, were the “sole”
inspiration for this project.
Scope
of Work
Every student is responsible for creating the
stickiest surface possible by maximizing the coefficient
of friction (pronounced mu). The student
will then create a software program that calculates
mu for any given surface that is marketable to the
theatre industry.

Deliverables
Linoleum
Square
Ramp Friction
Software
Program
Digital
Portfolio
Requirements
The
Linoleum Square must be:
-- Viscous due to ONLY food or drinks (No gum or taffy)
-- Free of fowl odors. Sticky not stinky!
-- Free of potential mold
The
Ramp Friction must be completed before testing linoleum square.
The
Software Program must:
-- Calculate Coefficient of Friction (mu)
-- Have entry fields for the angle (in degrees) of the ramp
and the mass (in kg) of the hockey puck
-- Display generated values, such as theta (in radians),
W (in N & lbs), Ff (N), FN (N), & mu
-- Calculate % increase from Control mu to Sticky mu
-- Be a User-Friendly, and
-- Exceeding Expectations: Have Bonus Features (if possible)
The
Digital Portfolio must include:
-- Product name, description, and features (including
Bonus)
-- A working hyperlink to the software program
-- Equations used and assumptions made
-- An image of the Research & Development (R&D)
test equipment
-- Discuss the values of sticky & control mu
-- Discuss the % difference
Grading
Criteria
The
varying weights for the following criteria will determine
the overall grade.
-- Coefficient of Friction & Software Program
-- Thoroughness & Thoughtfulness
-- Deadline & Deliverables
-- Work Ethic & Behavior
-- Bonus Features (if possible)
Safety
By
participating in Science Friction, the students are agreeing
to all the safety issues discussed in class.
