Total energy is the sum of the kinetic and potential energy in a mechanical system that has no external forces, e.g. a planet in orbit round the Sun.
Mechanical Energy
If the object is moving, it's kinetic energy, if the object for instance is at the top of a slide it's potential energy.
If the object is moving, it's kinetic energy, if the object for instance is at the top of a slide it's potential energy.
Because it's the sum total of the energy found in a mechanical system: in other words, the motion or position of an actual object.
the total energy from molecular motion.
the total energy of motion and position is called potential energy.
