The Theory of the Conservation of Energy states -
a)
Energy can be created, just not destroyed. It changes its form from one type to another.
b)
Energy can never be created nor destroyed. It can only change its form from one type to another.
c)
The total energy in our Universe changes, as different forms of energies can be transformed from each other under certain circumstances.
d)
Energy transformations do not passively occur in our lives, rather we actively make use of energies and transform energies.
