What type of energy is defined as the energy of objects that are moving?

The correct answer is mechanical energy because it specifically refers to the energy that an object possesses due to its motion and its position. Mechanical energy is commonly divided into two forms: kinetic energy, which is the energy of motion, and potential energy, which is the stored energy based on an object's position. When we talk about the energy of objects that are moving, we are primarily referring to kinetic energy, which is a key component of mechanical energy.

In contrast, electrical energy involves the movement of charged particles, typically in the form of an electric current, and does not inherently pertain to the motion of physical objects. Chemical energy relates to the energy stored in the bonds of chemical compounds, released during a chemical reaction, and nuclear energy is associated with the energy contained within the nucleus of an atom. Neither of these forms directly relates to the motion of physical objects like mechanical energy does. Thus, mechanical energy is the most accurate representation of the energy of moving objects.
