When you push on an object or surface (including standing on the ground), a force called the normal force exerts an opposite and equal amount of force. You only feel contact forces, like a dodgeball hitting you in the shoulder, or the ground pushing up against your feet (which we've learned is called the normal force). It is a force that acts at a distance, and it's impossible to feel. Figuring out exactly how much force he needs to pull the train up the hill is complicated and beyond our scope here (there are different kinds of friction involved, we don't know how much the train cars weigh, and so on). Crash enough particles and some of them will turn out to actually be on the other side when measured. What follows are questions that will test your knowledge of aftermarket parts and the companies that produce them. Some of these might be household names while others are known only to a select few who appreciate automotive excellence that passes others by - often literally. While Homer's flight (and the flight of his potato chips and ant overlords) is accurate, your ideas about why Homer and real astronauts are weightless in orbit might not be.
