G3的自然科學實驗課~~電荷

在電磁學裡，電荷Electric Charge是構成物質的基本粒子的一種物理性質，原子中的質子和電子分別帶有正電荷和負電荷，兩個帶電粒子之間會互相施加作用力，電荷符號相同的粒子會相互排斥，電荷符號不同的粒子會相互吸引。 基於此原理，我們以氣球作為介質，用不同的材質如: 衣服、塑膠和布的摩擦來進行實驗。第一個實驗是摩擦後的氣球會吸引髮絲；第二的實驗是同樣用塑膠袋摩擦的氣球會產生相斥的現象；第三個實驗是使用不同材質布及塑膠袋摩擦的氣球會產生相吸的現象

G3 Science Experiment Class: Electric Charge

In electromagnetism, electric charge is a physical property of elementary particles that make up matter. Protons in atoms carry a positive charge, while electrons carry a negative charge. Two charged particles exert forces on each other: particles with the same charge repel each other, while particles with opposite charges attract each other. Based on this principle, we use a balloon as a medium to conduct experiments by rubbing it with different materials, such as clothes, plastic, and fabric. In the first experiment, the balloon attracts hair after being rubbed; in the second experiment, two balloons rubbed with plastic bags exhibit repulsion; and in the third experiment, balloons rubbed with different materials like fabric and plastic bags show attraction.
