Njengoba kunikezwe lesi sigaba esiphathelene nokulingana kweMass<unk>energy, ngitshele ukuthi ingxenye ngayinye ye-equation ethi E=mc2 imelelani.
Context:Le fomula ichaza amandla E enhlayiyana esesimweni sayo sokuphumula njengomkhiqizo wobuningi (m) ngesivinini sokukhanya sikwele (c2). Ngenxa yokuthi isivinini sokukhanya siyinombolo enkulu ngamayunithi asetshenziswa nsuku zonke (cishe 300000 km/s noma 186000 mi/s), ifomula isho ukuthi inani elincane "lemisa lokuphumula", elilinganiswa lapho isimiso siphumile, lilingana nenani elikhulu lamandla, okuyinto engahlobene nokwakheka kwendaba.
U-E ungamandla, u-m ungubukhulu, futhi u-c2 uyisivinini sokukhanya sikwele
