Sentences with phrase «mechanical energy»

Mechanical energy refers to the energy possessed by an object due to its motion or position. It can be thought of as the combination of two types of energy: kinetic energy, which is the energy of an object in motion, and potential energy, which is the energy stored in an object based on its position or condition. Full definition

The second process is anelastic behavior of an icy body, which is its ability to turn periodic mechanical energy (from tides, for instance) into heat.
However, this light energy is not totally dissipated: it is turned into mechanical energy through the twisting of the polymer chains, and stored in the gel.
Devices to harvest ambient mechanical energy to convert to electricity are widely used to power wearable electronics, biomedical devices and the so - called Internet of Things (IoT)-- everyday objects that wirelessly connect to the internet.
