Video Based Motion Analysis Tetyana Antimirova and Marina MilnerBolotin, Department of Physics Faculty of Engineering, Architecture and Science Ryerson University OAPT Conference, May 22-24, 2008

WHAT IS VIDEO-BASED MOTION ANALYSYS? In Motion Video Analysis, experimental demonstrations or real-life events involving motion (roller-coaster rides, car race, sports events, objects falling, etc.) are recorded on

videos and later analyzed using Logger Pro or VideoPoint software The position data are collected from each time frame

Positions of objects in the video frame can be measured by pointing a mouse and clicking. The data generated can be graphed, analyzed in spreadsheets, compared to theoretical models.

ADVANTAGES Demonstrates real event (as opposed to idealized textbook end-of-chapter questions) The data for problems/modeling come from

the experiment A Video Analysis mini-project presents a feasible cost effective alternative to live experiments.

Works whenever visible motion takes places Data Acquisition and Analysis Software from Vernier (LoggerPro) David Vernier www.vernier.com

/ TETYANAS FIRST TRY Tetyanas first attempt at motion video analysis at summer ActivityBased Physics Faculty Institute

(ABPFI), Dickinson College, Carlisle, Pennsylvania, June 2007 EXAMPLES Cart Going Forth and

Back Cart Going Forth and Back Incline Free Fall

VIDEO FROM CONTEMPORARY GALILEOS PROJECTILE HOMEWORK (Courtesy of Activity Based Physics Group) Frame-by-frame traced trajectory TWO-TRACKS DEMO FROM ONTARIO

SCIENCE CENTRE Question: Two metal balls are released from the the top point simultaneously. Which one will finish first?

HOMEWORK Some of the traditional end-ofchapter problems can be converted into motion video analysis problems

Additional benefit: comparison of analytical solutions (whenever possible) with numerical solutions/modeling using real data MANY STUDENTS FAIL TO RECOGNISE THE SIMILARITIES BETWEEN THESE SITUATIONS

TRADITIONAL END-OF-CHAPTER PROBLEM A package is dropped from the plane which is flying with a constant horizontal velocity of Va=150 ft/s. Determine the normal and tangential components of acceleration, and the radius of curvature of the path of motion just before the package strikes the ground R.C Hibbeler, (2006), Engineering Mechanics, Pearson

PROBLEM EXAMPLE Based on what you know about curvilinear motion, calculate the rate of increase of speed for the third last point of the trajectory (t=0.917). Whenever possible, use real data from the movie. (was offered as a supplement to the ABPs

Galileos Projectile II: Using Contemporary Techniques assignment) THE PROJECTILE PATH TRACED HORIZONTAL MOTION

VERTICAL MOTION VIDEO-BASED MOYION ANALYSIS Potential to captivate and engage the students

Potential to use whenever the visible motion takes place HANDS-ON PART

Recoding our own video and inserting it into LoggerPro Analyzing movie using LoggerPro THANK YOU!
