Atoms are composed of three particles with an electric charge: electrons, protons and uncharged neutrons. Electrons have a negative charge, and protons have a positive charge. The negative charge of ...

It’s a fundamental principle of physics that particles with opposite charges attract each other, while those with the same charge repel. But now, scientists at the University of Oxford have found that ...

The Saarland researchers reveal that the slipperiness of ice is driven by electrostatic forces, not melting. Water molecules in ice are arranged in a rigid crystal lattice. Each molecule has a ...

The amazing ability of some geckos to scale smooth walls and cling to ceilings could be primarily a result of contact electrification. That is the claim of researchers at the University of Waterloo in ...

Physics Problem: Calculating the maximum force between two electric charges! ⚡🔋 In this video, we’ll break down how to calculate the maximum force between two point charges using Coulomb’s Law.
