Factor of adhesion

Adhesion is like magnets! It's the strong attraction between two surfaces that hold them together. When you stick two magnets together, that's adhesion in action. Adhesion is important in all kinds of ways, especially in engineering. For example, adhesion helps make things like airplanes and bridges stronger and more durable. To make sure two surfaces really stick together, engineers use things called "factors of adhesion." These are like tools that help them measure how well the two surfaces are sticking together and make sure they stay connected.
