"The difficulty is to combine conflicting properties." Scientists develop mysterious new material that could transform energy ...

A stretched or squashed object has more energy in its elastic energy store. The amount of energy in the elastic energy store depends on the amount of extension or compression. In the 18th century ...

Kinetic energy, i.e., motion energy or the corresponding mechanical work, is converted into elastic energy in such a way that it can be fully released again when required.

An elastic object, such as a spring, stores elastic potential energy when stretched or squashed. The extension of an elastic object is directly proportional to the force applied. This equation ...
