1. The Effectiveness of Packaging Materials and Box Sizes on the Net Acceleration of a Fallen Object Luke Emery & Kyla Semones Cousino High School

2. 2

3. Purpose Helping engineers use the most cost effective and environmentally- friendly way of transporting objects while at the same time decreasing its acceleration once it falls. 3

4. What is a package? Keeps objects safe Holds fragile objects together Prevents objects from shattering Capable of traveling across seas 4

5. Why is packaging material important? Protects fragile objects from breaking Capable of horrid outcomes Can cause objects to fall slower 5

6. What determines box size? The size of the object being shipped iPhone vs. large desk 6

7. What is net acceleration? 7

8. How was net acceleration measured? Three-axis accelerometer Accelerometer measures from three different axes 8

9. Momentum, p △ p = Ft What is impulse? 9

10. Problem Will different packaging materials and box sizes decrease the net acceleration of a fallen object? 10

11. Predicted Outcome The accelerometer packed in the small cardboard box with the cardboard squares will fall with the slowest net acceleration. 11

23. Conclusion Original hypothesis was accepted The accelerometer packed in the small cardboard box with the cardboard squares produced the lowest net acceleration 23

24. Experimental Flaws Packing time Dropping height Calculating 24

25. Errors Accelerometer placement 25

26. Errors Cardboard squares insufficiency 26

27. Errors Tissue paper 27

28. Discoveries Importance of packaging material in a box FedEx and UPS workers are not the most trustworthy 28

29. Further Research FedEx and UPS Use of “greener” materials shows innovation in the packing industry Majoring in packaging Engineering behind packaging 29

30. Recap How packaging materials and box sizes affect the net acceleration of a fallen object Found net acceleration from a three-axis accelerometer Calculated net acceleration using maximum accelerations 30

31. Recap Box size proved to have a negative effect on net acceleration Box size (-) and cardboard squares (-) had the lowest net acceleration compared to other materials 31
