💫Spinning coin inside a balloon experiment. 🌀Experiment on centripetal force.
- The coin was set in motion by the initial force provided by the rotation of the balloon, and the shape of the balloon helps the movement of the coin to a circular path. - There is also a slight friction force between the edge of the balloon and the coin, which slowly helps in stopping the balloon from spinning. - Another force is that of gravity, which pulls down the coin. - But the force which helps the balloon spin into circles is centripetal force. 🧪Materials required- 1. A Coin • 2. A Balloon
UKnoWhat? on Instagram: "✅ Follow us ✅ Magic of Refraction!! In a situation where the glass and the liquid have matching refractive indices, the light passing through does not bend at the interface between the glass and the liquid. This lack of refraction means that there's no visual cue to indicate the presence of the glass, rendering it effectively "invisible" to the naked eye.
