Internal: energy present within molecules in form of kinetic due to motion of particles in matter and potential depending on separation between molecules
sound
Radiant: in the form of electromagnetic waves e.g. x-rays, infrared, visible etc.
Electrical: due to charge or current
Gravitational Potential: possessed by an object by virtue of its position in a gravitational field
Elastic: possessed by an object by virtue of its state of deformation
Chemical: possessed by a fuel by virtue of its chemical composition
Nuclear: energy in nucleus of atoms due to nuclear composition
Sources of energy that can be replaced or replenished each day by earth's natural processes
Efficiency = useful energy/power output / total energy/power input x 100%
The efficiency of a system isthe ratio of the useful energy output from the system to the total energy input.
Energy efficiency
If a system has high efficiency, this means most of the energy transferred is usefulIf a system has low efficiency, this means most of the energy transferred is wasted
Sources of energy that are finite and cannot be renewed everyday because it takes million years to replace them
