PE (potential energy) + KE (kinetic energy) will equal ME (mechanical energy) ... explain this in your own words, or by using an example.

Potential energy plus kinetic energy equals mechanical energy because mechanical energy is basically just all of an object's energy, it's just two kinds of energy. The potential is stored inside and kinetic is being used. Both of those together is the total amount of the objects energy, which is the mechanical energy.
