Conservation of Mechanical Energy
Total mechanical energy is conserved in absence of non-conservative forces.
Variables
KE₁J
Initial kinetic energy
KE at position 1
PE₁J
Initial potential energy
PE at position 1
KE₂J
Final kinetic energy
KE at position 2
PE₂J
Final potential energy
PE at position 2
Derivation
When only conservative forces act, E_total = KE + PE = constant.
