Mechanical Energy and Its Conservation
Note that these laws apply to conservative forces only
General Form of the Work Energy
Principle
ΔKE + ΔPE = 0 or (KE2 - KE1) + (PE2 - PE1) = 0
Total Mechanical Energy, E
E = KE + PE
From the General Form Above KE2 + PE2 = KE1 + PE1 Or E2 = E1 = constant Total Mechanical Energy is Conserved
