All of us have seen a Jack-in-the-box. It is fun to watch it spring up when the box is opened.
Have you ever wondered how and why the jack jumps up? The jack in the box has energy stored in it. When we push the jack into the box, we use our energy.
This energy is stored in the jack in the form of kinetic energy. It is released when we open the box.
