Alkaline batteries (and others) are useful because they store energy. You could use this energy to power a robot or maybe even a radio. Chances are that whatever you might want to do, a battery might ...

There are “costs of life” that mechanical physics cannot calculate. A clear example is the energy required to keep specific biochemical processes active — such as those that make up ...

In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects interpretation of beta ...

Explore the relationship between spring force and potential energy in this physics breakdown! Learn how springs store energy, how Hooke's Law applies, and how to calculate the potential energy in ...
