Скачать или смотреть Can You Really Start a Fire With a Hammer?

When a hammer strikes a metal rod repeatedly, the mechanical energy of the hammer is converted into thermal energy, heating the rod. This mechanical energy, specifically kinetic energy, is transferred from the moving hammer to the atoms in the metal during each impact. As the hammer delivers forceful blows, it causes localized compression, deformation, and vibration within the metal. These atomic-level disturbances increase the internal energy of the rod, raising its temperature. Repeated hammering amplifies this effect, and the metal can become hot enough to ignite flammable materials. If a piece of cloth, such as cotton, touches the rod once it reaches its ignition temperature, it can catch fire. This demonstrates the transformation of mechanical energy into heat.
