Titanic baby mystery solved. The body of a baby boy buried as the Unknown Child has always been a poignant reminder of the tragedy of the Titanic. Five years ago scientists thought they had solved the mystery when DNA testing identified the victim as a 13-month-old Finnish baby.
Mechanical Energy. Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).
Energy has been defined as the capacity to do work. Energy exists in two forms potential and kinetic. Potential energy is the energy at rest {i.e., stored energy) capable of performing work. Kinetic energy is the energy of motion (free energy). It results in work performance at the expense of potential energy. Conversion of potential energy into kinetic energy involves the imparting of motion.
