A new kind of shape-shifting material can twist, bend, and snap into more than a dozen three-dimensional forms—no motors or wires required. Using stored elastic energy, it transforms itself much like ...

Illustrates how kinetic energy is transferred from one body to another through elastic collisions. Explains formulas for calculating the exchange of energy. Defines concepts concerning stored energy, ...

Potential energy is stored energy. Potential energy is the energy that exists by virtue of the relative positions (configurations) of the objects within a physical system. This form of energy has the ...
