It depends on the system they are in. For example, you can imagine a room with balls in it. While it's true that their kinetic energy is not bounded, they can't have arbitrarily big potential energy because of the ceiling. There are examples of such systems where the total energy of particles is bounded but none come to mind right now.
Good question. Atoms can be trapped in an optical lattice which consists of periodic potential (Quantum mechanics), which can be created by laser beams. It creates a band structure. This means the energy splits up in bands like for eg: Valence and conduction bands in a metal or semiconductor. Bands are separated by band gaps - Energy regions without any states for particles (particles cannot accommodate these gaps- quantum mechanics). Therefore, each band naturally has a lower as well as an upper bound for energy. While there is more to it, you can read about it more.

Man liked the end part of the video as it questions a wider aspect of this topic.
Loved the background music.

And so the wait was worth it. ❤️
How can particles have maximum possible energy?

sir please refer some good books for jee and olympiads
which class r u in?
@@krushnamali6183 im JEE 2025 aspirant pls recommend some good physics books. i score around 30-40 marks in physics jee adv mocks of allen
