When the elastic band is stretched, it stores energy, and the peg acts as a simple holding or release point. Once released, that stored energy transfers into kinetic energy, sending the lightweight match forward. The lighter mainly serves as a rigid frame to keep everything aligned, while the match’s low mass allows it to acceler
