Physics Lesson 6.1.4 - When Does an Object Start Falling Sideways?

Welcome to our Physics lesson on When Does an Object Start Falling Sideways?, this is the fourth lesson of our suite of physics lessons covering the topic of Centre of Mass. Types of Equilibrium, you can find links to the other lessons within this tutorial and access additional physics learning resources below this lesson.

When Does an Object Start Falling Sideways?

There are some examples in which objects are leaned but they still don't fall sideways (Leaning Tower of Pisa for instance). In other examples, objects start falling sideways despite they apparently seem at vertical position.

As long as the vertical line drawn from the centre of gravity falls inside the lower base of the object, it doesn't fall sideways. When the object leans at such an extent that the vertical line drawn from the object's centre of gravity falls outside its lower base, the object falls sideways. Look at the figure:
