After measuring with the 100-g mass of the building respond to the following questions as comments underneath the picture of your structure.
1) Is your building more or less stable when the mass is placed on higher floors?
2) Describe how the centre of gravity moves as the 100-g mass moves up each floor.
3) After you moved the 100-g mass closer to the edge of each floor rather than in the middle what differences did you notice in the stability of the building.
4) What changes could you make to your design that would make the building more stable when the centre of mass is high or near the edge of a floor?
