energy
is the stored energy in any object or system by virtue of its position or arrangement of parts. energy available to do work
potential energy
is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy. the energy of motion
kinetic energy
can we destroy and create energy?
no, we cant
inefficient conversion of energy causes?
entropy
there is a constant input of energy into the cell, entropy ensues, and the cell dies
