Reposted from Instagram @ explainlikeimfivee When a truck is stuck in gravel, its tires spin without moving the vehicle forward because they can't get a good grip on the loose surface. By placing a log between the tires, we're essentially giving the truck a temporary traction aid. Imagine you're trying to climb a rope but keep slipping. If you wedge a stick between your feet and the rope, you can push against it to get a better grip and climb up. Similarly, when a log is placed between the truck's tires, it acts as a solid surface for the tires to push against. As the tires spin, they grip the log instead of the loose gravel. This grip helps to propel the truck forward and out of the stuck position, just like using the stick helps you climb the rope. #science #physics #offroading #explore #viral
