Question

Which of the following is the correct definition of mechanical energy? A. energy stored in chemical bonds of molecules B. energy an object has because of its motion or position C. energy of an object due to the random motion of its atoms and molecules D. energy resulting from the flow of charged particles, such as electrons or ions

Answer 1

The correct answer is B. Energy an object has because of its motion or position

Explanation:

In physics, the mechanical energy of a body or object is determined by the position and/or motion. Due to this, the mechanical energy includes both the kinetic energy (energy during movement) and the potential energy (energy according to location or stored energy). Additionally, the mechanical energy as other types of energy is constant if no forces are acting over it in an ideal system, but in reality, this type of energy is influenced by external forces, for example, friction. Thus, the correct definition of mechanical energy is " Energy an object has because of its motion or position".
