Happy/Sad balls can come after demonstrating the large/small balls collision so the students have seen how energy can transfer and how it remains conserved. But, there's an alternate from all forces on the ball. Since both balls are elastic, both rebound to their original shapes. Since the sad ball stores its energy far more than the happy ball, that energy is not being transferred in the collision, which is why it appears to be an inelastic collision. The amount of energy dissipated depends on the material the object is made out of. What the heck! should be equal and opposite. to have two different sides, so this has to be a negative Again using metaphors of common day situations helps.
