Engineering is about designing and applying scientific knowledge to solve problems in real-life. In this problem, the children have to complete building the vehicle and think of ways to increase the friction or drag on the vehicle so that it slows down sufficiently and hits the stopper with minimal force, without breaking the egg. When the egg car is at the top of the ramp, it has a specific amount of potential energy depending on the height of the ramp and the mass of the egg car. One of two things can happen to this energy, it can turn into kinetic energy or heat energy as the car is released. If there is very little friction between the ramp and the egg car, very little energy will be converted into heat and the egg car will have too much kinetic energy, travel too fast, and the egg will break.
