======================== usaha usaha = gaya x perpindahan usaha = [M][L][T]⁻² [L] = [M][L]²[T]⁻²
=========================== energi potensial EP = MGH EP = kilogram*meter/sekon² . meter EP = kilogram*meter² /sekon² EP = kilogram*meter² *sekon⁻² EP = [M][L]²[T]⁻²
percepatan = kecepatan/waktu = m/s^2
percepatan = [L][T]⁻¹/[T] = [L][T]⁻²
=======================
gaya
F = M x A
F = [M] [LT-2] =[MLT-2]
========================
usaha
usaha = gaya x perpindahan
usaha = [M][L][T]⁻² [L] = [M][L]²[T]⁻²
===========================
