Energi: Perbedaan antara revisi

Dalam [[fisika]], '''energi''' adalah [[properti fisika]] dari suatu [[objek fisik|objek]], [[perpindahanawwwwpindahan energi|dapat berpindah]] melalui [[interaksi fundamental]], yang dapat [[transformasi energi|diubah]] [[bentuk-bentuk energi|bentuknya]] namun [[konservasi energi|tak dapat diciptakan maupun dimusnahkan]]. [[Joule]] adalah satuan [[SI]] untuk energi, diambil dari jumlah yang diberikan pada suatu objek (melalui [[kerja mekanik]]) dengan memindahkannya sejauh 1 [[meter]] dengan gaya 1 [[newton (satuan)|newton]].<ref>Energy units are usually defined in terms of the [[Work (physics)|work]] they can do. However, because work is an indirect measurement of energy, (One example of the difficulties involved: if you use the [[first law of thermodynamics]] to define energy as the work an object can do, you must perform a perfectly [[Reversible process (thermodynamics)|reversible process]], which is impossible in a finite time.) many experts emphasize understanding how energy behaves, specifically the [[conservation of energy]], rather than trying to explain what energy "is". {{cite web|url=http://www.colorado.edu/physics/phys1110/phys1110_fa10/Feynman_energy.pdf|title=The Feynman Lectures on Physics Vol I.|accessdate=3 Apr 2014}}{{Pranala mati|date=Maret 2021 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>
