Comment calculer la vraie vitesse d’un train miniature ?

We're going to talk about model trains and physics at the middle and high school level: Using cross-multiplication and concrete examples, we can determine if a model train is traveling at the correct speed. We'll work on the concepts of scale, proportionality, speed calculation, and conversions between km/h and m/s. So whether you're a model railway enthusiast or a middle and high school student who loves physics and chemistry, this is for you! 😁👍 --- 🧪 All videos are categorized by theme and level, and all links to the social networks are available here: https://physicochimicomethodo.fr/ 🧪 To subscribe:    / @physicochimicomethodo   Jmbé Media - PCM 2025
