Wobbly arrows launch faster than rigid ones ― as long as they have weighted tips 1. Studies have shown that launching devices, such as bows, impart more energy to flexible objects than to rigid ones, ...

Potential energy is the latent energy in an object at rest, and is one of two forms of energy. The other form, kinetic energy, is the energy expressed by an object in motion. Potential energy is a ...

Harnessing abundant but inaccessible energy from unlikely sources may soon be as simple as taking a walk in the park. Researchers at the University of Wisconsin-Madison have developed a new method of ...

Fusion energy, the result of two lighter atoms coming together to form a heavier one, can release massive amounts of energy without harmful carbon pollution, making its potential widespread use a goal ...
