What is the conservation of mechanical energy is defined as? A. The sum of the kinetic and potential energies of an object remains a constant value unless there are forces acting on the object that cause a loss of energy overall, such as friction and air resistance

B. Energy of motion

C. Law of conservation of energy

D. Potential energy added to kinetic energy

A. The sum of the kinetic and potential energies of an object remains a constant value unless there are forces acting on the object that cause a loss of energy overall, such as friction and air resistance

Explanation:

Mechanical energy is of two forms; Kinetic energy and Potential energy.

These two forms of mechanical energy can be interconverted bete themselves. This means that potential energy can be transformed to kinetic energy and vice versa. During these transformations, the sum remains constant. This is known as the law of conservation of mechanical energy.

The law of conservation of mechanical energy is derived from the law of conservation of energy which states that, in a closed system, total energy is conserved—that is, it is constant. A closed system is one in which no energy is lost to the surroundings due to friction and air resistance.

Therefore, the law of conservation of mechanical can be stated as; The sum of the kinetic and potential energies of an object remains a constant value unless there are forces acting on the object that cause a loss of energy overall, such as friction and air resistance.
