What is the energy of an object because of its potential and kinetic energies?
o
chemical energy
electrical energy
nuclear energy
mechanical energy

It's mechanical energy.

Explanation:

Potential and kinetic energies have to do with an objects movement or potential to move, or mechanics.

Mechanical energy

Explanation:

 The mechanical energy is basically the sum of the kinetic and the potential energy. This type of energy is basically associate with both the position and motion in the object.

The main principle of the mechanical energy is that in the isolated system, the mechanical energy are constant due to the conservation forces.

In an object, the motion of an object posses the kinetic energy and the position of an object are the potential energy so this object is the combination of both the energy which is known as mechanical energy of an object.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
