Physics Uncovered on Instagram: "Electrostatic friction is one of the subtle forces that helps objects stay put — even when the surface seems smooth. When two materials come into contact, electrons can transfer between them. This creates tiny patches of positive and negative charge. Those opposite charges attract each other, adding a small “electrostatic grip” on top of normal friction. That’s why things like paper, plastic, or your phone case sometimes cling to a table, a screen, or even your c

Explaining The Universe on Instagram: "Centripetal force is the inward-directed force that keeps an object moving along a curved or circular path instead of flying off in a straight line. Whenever something turns—like a car rounding a corner, a ball being swung on a string, or a planet orbiting the Sun—it requires a constant pull toward the center of the circle to maintain that motion. This inward force can come from different sources, such as friction, tension, or gravity, depending on the situ
