Mechanical Energy Calculator
Calculate total mechanical energy as the sum of kinetic energy and potential energy. ME = KE + PE.
Enter mass, velocity, and height.
Mechanical Energy Formula
ME = KE + PE = ½mv² + mgh
Example: m = 2 kg, v = 4 m/s, h = 5 m
KE = ½×2×16 = 16 J, PE = 2×9.81×5 = 98.1 J
ME = 114.1 J
KE = ½×2×16 = 16 J, PE = 2×9.81×5 = 98.1 J
ME = 114.1 J
FAQ
Is mechanical energy always conserved?
Only in the absence of non-conservative forces (like friction). In reality, some energy is always lost to heat or sound.
