Mechanical work
Work is defined as "an integral limit" as far as the force F s
Kinetic energy
Kinetic energy is the energy associated with the motion of an object.
Potential energy
In contrast to the kinetic energy, which is energy due to the motion of a system, or the internal movement of particle, the potential energy of a system is the energy associated with the space configuration of its components and their interactions with each other. The number of particles that emit the style to each other automatically form a system with potential energy. The styles, for example, can arise from electrostatic interactions (see Coulomb's law), or gravity.
Internal energy
Internal energy is the kinetic energy associated with the motion of the molecules, and the potential energy associated with the vibrational and electric energy of rotation of the atoms in the molecule. The internal energy as energy is a function of the circumstances that can be calculated in a system.
