The limits of friction

Friction is created when two surfaces slide one on top of the other. Since this consumes additional energy, this so-called sliding friction is considered an irksome yet inevitable aspect of dynamic processes. However, to ...

Why does a spinning egg stand up?

If a hard-boiled egg is spun fast enough on a table, it will slowly stand upright as it continues to spin. Although the spinning egg rises due to the force of friction between the egg and the table, the full explanation involves ...
