Mechanical Energy

What is mechanical energy

Mechanical energy is the ability of a body to generate movement and perform mechanical work.

Mechanical energy is the basis for understanding in mechanics or the study of the movement and rest of objects and the forces that influence them, the movement geometry (kinematic mechanics) and the balance science (static dynamic mechanics).

The mechanical energy of any object is the sum of two types of energy:

  • The potential energy (Ep): that which is but has not been used for a certain purpose, such as the strength of a water source; Y
  • The kinetic energy (Ec): the application of forces to animate and accelerate the mechanism, such as the energy of the water source retained by the turbines.

The forces that influence the movement or rest of a body are potential energy and kinetic energy, therefore:

Em = Ep + Ec

Mechanical energy obeys Principle of conservation of energy which stipulates that “energy is neither created nor destroyed, it is only transformed” therefore the different types of potential energy that can exist in a body must be taken into account, such as:

  • The elastic potential energy: indicates the position of the body with respect to the energy or force stored in its elastic property.
  • The gravitational potential energy: Gravity plays an important role in the position of the body.
  • The electric potential energy: The electrical capacity according to the place where the object is located.
