"Eventually, [[Isaac Newton]] (1643–1727) **laid down fundamental physical laws involving mass, force, and momentum, and his second law of motion made it possible to derive the basic energy units.** "Using modern scientific units, **1 joule is the force of 1 newton—that is, the mass of 1 kilogram accelerated by 1 m/s2 acting over a distance of 1 meter.**" ([Location 582](https://readwise.io/to_kindle?action=open&asin=B08SGC3TD3&location=582)) --- **Tags** -- [[quotes]], [[physics]], [[energy-conversion]], [[units-of-measure]], [[joules]], [[newtons]], [[kilograms]], [[meters]], [[mass]], [[force]], [[momentum]] **Source** -- [[202412030828 - B - How the World Really Works]]
