Mechanical energy can be calculated as the sum of the object's kinetic energy (KE) and potential energy (PE), where KE = 0.5 * mass * velocity^2 and PE = mass * acceleration due to gravity * height. The total mechanical energy is the sum of the object's KE and PE at a given moment.
There is no special formula for that: if you convert KE to PE, every joule of KE becomes one joule of PE. For practical calculations, you often have to use the KE and PE formulae separately.
mass is most often measured in kg in science
