I've seen an online definition:
A collision in which potential energy is converted into kinetic energy so that the total kinetic energy of the colliding objects is greater after the collision than before.
And I've looked online online a lot, but I still don't really grasp the idea.
Can someone explain it to me whilst giving me multiple examples?
EDIT: Thank you for the answer @AliMoh but I think you just added to my confusion, I've heard of of two examples, I've heard "Basically, it's like a bomb or explosion", and I've heard "Imagine two karts colliding together" and now this, I still don't understand, or rather, I'm confused.
EDIT2: Thanks @SirElderberry and @AliMoh , both of you really helped me understand, but just to clear up and state why I was confused in the first place (I know this goes against the rules, but bear with me), I'm doing this for a multiple choice homework, and two of the answers seem correct (According to my understanding right now) So would a falling grenade AND two colliding bicycles be superelastic collisions? (You don't have to answer this, I'll just assume the question is wrong and blame my teacher)
EDIT3: I REALLY like both of your answers, but I have to choose just one as the correct answer... I want to credit both of you though, and I don't want one of you to feel left out or inferior cause you both helped...
