The world needs a new source of energy, an unspillable source.

How are the Laws of conservation of Energy and Momentum similar?

How are the laws of conservation of momentum and energy similar?

Here are the formulas:

Law of conservation of momentum:

P1 + P2= P1′ P2′

m1 v2 + m2 v2 = m1′ v1′ + m2′ v2′

Law of conservation of Energy:

KEi + PEi = KEf + PEf
I think that the energy can’t be created nor distroyed but it can be transformed from one form to another.
But is that the similarity???
