    Imagine a bundle of fibers, like a rope. The fibers are held together by cohesion, which provides the strength and flexibility of the rope. However, when you try to attach a hook to the rope, the adhesion between the rope and the hook comes into play. The strength of the attachment depends on the adhesion between the two materials.

    Cohesion refers to the forces within a material, while adhesion refers to the forces between different materials.
