The force that helps hold things to the fridge door is typically magnetism. Many refrigerators have magnetic strips on the door which attract magnets on items like paper notes, pictures, or magnets. This magnetic force helps keep these items in place on the fridge door.
A list of supplies needed for an experiment is commonly referred to as a "materials list" or "materials required." This list outlines all the items, equipment, and substances necessary to conduct the experiment successfully. It helps ensure that researchers have everything they need before starting the experiment.
