Wood has "potential" energy while a burning fire has "kinetic" energy.

Potential energy is characterized as a put away vitality, while dynamic energy is found in movement. Kinetic energy can be seen on numerous scales, regardless of whether it's the vibrating of particles creating heat, or long wavelength radio waves. When taking a gander at energy it is critical to take a gander at the law of conservation of energy . This physics law expresses that vitality can't be made nor devastated, however can just change starting with one shape then onto the next (i.e. abandoning potential energy to kinetic energy ). On account of consuming wood, put away potential energy in the log is discharged because of warming by other energized molecules. This compound response is called combustion and requires oxygen.
