thumb|upright=1.3|alt=A tabby cat covered in packing peanuts.|Foam peanuts clinging to a cat's fur due to [[static electricity. The cat's fur becomes charged due to the triboelectric effect. The electric field of the charged fur causes polarization of the molecules of the foam due to electrostatic induction, resulting in a slight attraction of the light plastic pieces to the fur. This effect is also the cause of static cling in clothes.]]
Electrostatics is the study of electric charges that build up on objects and the forces they create, such as when friction causes a cat's fur to become charged and attract lightweight materials like foam peanuts. Understanding electrostatics matters because it explains everyday phenomena like static cling in clothes and helps us understand how charged objects interact with their surroundings.

靜電學是研究「靜止電荷」的特性及規律的一門學科，電學的領域之一。靜電即電荷在靜止時的狀態，沒有電荷流動。而靜止電荷所建立的電場稱為靜電場，是指不隨時間變化的電場，該靜電場對於場中的電荷有作用力。
