Positive and negative sides of inertia.

Inertia is an elementary physical phenomenon. All objects have this property. Inertia, like everything that happens in this world, has two sides: positive (beneficial) and negative (creating adverse consequences). Thanks to this phenomenon, people have the opportunity to engage in many sports, internal combustion engines work properly, inertia is simply necessary for the operation of navigation systems and vehicles. But moving bodies cannot be stopped instantly, which leads to dire consequences. Because of inertia, accidents happen, people get injured, tsunamis and earthquakes cause great harm and death.
