Lesson 2 : STANDING TALL and LYING LOW
There are a numbers of factors which affect the stability of an object.
1. The base area.> The bigger the base area, the more stable the object is.
2. Height> The higher the object, the less stable it is.
3. The materials used.> Example of materials used for construction are concrete, wood, steel and plastic.

BASE AREA
A bottle in an upright position has a bigger base area. It is therefore more stable than a bottle in
an upside down position.
