What is the energy of an object because of its potential and kinetic energies?

chemical energy

electrical energy

nuclear energy

mechanical energy

The correct answer is "mechanical energy".

Explanation:

Mechanical energy is the strength that an object has because of its movement and position. Mechanical energy is the sum of its potential energy (energy of position respect to other objects) and kinetic energy (energy of motion or movement). An example of mechanical energy is the one that exerts a baseball player when he hits a ball with his bat.

mechanical energy because when the object falls the potential energy deceases and the kinetic energy increases.
