Energy Smart

~Fefi~ asked:


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???
