Which force plays the smallest role in everyday objects?

For everyday objects like chairs, books, or electrons, gravity is far weaker than the electromagnetic forces that hold matter together. That is why static electricity, friction, and chemical bonds can easily overpower the gravitational pull between small objects. Gravity becomes dominant only when huge amounts of matter are involved, such as planets and stars. This is why a magnet can lift a paperclip against Earth’s gravity so easily. The contrast between gravity and electromagnetism is one of the great scale-dependent features of nature.
