Gravity. Walking is a series of falls, to fall up a hill you must cheat a bit - by leaning forward.
How will breaking and steering the car affect the cars balance?

How do roller coasters roll?
They roll on small wheels. :) The cars are pulled (or pushed) to the top of the first hill on the track. Traditionally it is pulled to the top by a chain in the track that is driven by a motor on the ground. The first hill is always the highest point on the track, thus the cars can "coast" down the rest of the track. If one of the later hills were higher than the first hill, then the cars would not be able to coast to the top of the higher hill. When ever the cars go down, they gain enough speed to coast to the top of the next hill.
What is a railroad hump yard?
It's a yard with a hill. Cars to be classified are pushed up the hill and released. Gravity moves the cars downhill, and a series of switches sets which track the car rolls into.
Why do you think that the first hill on the roller coaster must be the tallest Explain in kinetic and potential terms?
When the cars go up the first hill, energy is put into the system through some machine (what pulls the cars up). From here on out, there are usually no more additions in energy to the system. Thus, at the top of the first hill, the cars have the highest potential energy. As the cars move down the first hill and up the second, some of the energy is lost through the heat given off by friction. So, the total energy of the system goes down. This means that, after each hill, the cars will have less energy and cannot go up a hill the same height as the first. Since the cars lose kinetic energy through friction, each hill must be smaller than the last until the ride ends or another booster puts more energy into the system.
What happens to toy cars when the second hill is set to 100 cm?
When toy cars go down a steep hill they pick up momentum. Which makes them go faster so a car on a steeper hill will go faster then one on a flat surface.
Is a car driving up a hill projectile motion?
No. The car is applying a force to keep going up the hill and the hill and car are providing forces to keep it up.
