![]() The bowling ball starts with a certain amount of potential (stored) energy. ![]() ![]() To change the energy of something, you have to move it (for example, give it a push). The total amount of energy an object has stays the same, unless you do something to change it. ![]() Quick Physics: Conservation of Energy tells us that the bowling ball will not go higher than its starting height (without some external force pushing on it).Ī swinging bowling ball illustrates a very important principle of physics: The Conservation of Energy. The Demo: A volunteer stands with their nose to a bowling ball that is suspended from the ceiling, and then lets go.
