Do formless emotions emanate some form of energy ?

I was sitting in a library just about to get going on my work when I suddenly noticed a door open and a gush of happy energy in the forms of smiles, laughter, and warmth just swept the entire floor. It was the activity room in the library from where young mothers with their toddlers were making their way. Each mother walking precariously just behind her bundle of joy, who was rolling down towards an exit gate in Brownian motion. Some mothers looked anxious, some were smiling but the aspect that made all of them look so similar was that they were all rapt in their task at hand watching over their young one. The children on the other hand also shared a similarity – they all looked happy and carefree. Just watching these events unfold makes one elated and in some way hopeful, happy & energized. Newton had talked about the energies of the physical world – matter & motion, Maxwell uncovered the energies of the unseen Electrical and Magnetic waves, I think it’s time some scientist/Philosopher unravels the mysterious energies intertwined in the metaphysical world of emotions.
