What type of object is generally considered unstable?

An object that is heavier at the top is generally considered unstable due to its design concerning the center of gravity. When the center of gravity is located above the base of support, the object is more prone to tipping over. This is because the gravitational force acting on the object creates a torque that increases as the object leans away from its vertical position.

In contrast, objects that are heavier at the bottom or have an equally distributed weight maintain a lower center of gravity, enhancing stability. For instance, a pyramid shape, which is heavier at the base, is significantly stable compared to an inverted pyramid, which would be top-heavy and thus highly unstable. Understanding the principles surrounding the center of gravity is essential for safe practices in operating equipment such as lifts and cranes, where the stability of the load can impact overall safety.
