What is the lift hill mechanism on roller coasters?
Lift hills usually propel the train to the top of the ride via one of two methods: a chain lift involving a long, continuous chain which trains hook on to and are carried to the top; or a drive tire system in which multiple motorized tires (known as friction wheels) push the train upwards.

Chain Lift – This is the most traditional way of getting the train to move up the lift hill. ... Catapult-launch Lift – This is another way of moving the train up a hill in newer roller coasters. ... The Brake System – A roller coaster uses a brake system to slow down or stop it.
A roller coaster does not have an engine to generate energy. The climb up the first hill is accomplished by a lift or cable that pulls the train up. This builds up a supply of potential energy that will be used to go down the hill as the train is pulled by gravity.
The first hill of a roller coaster is always the highest point of the roller coaster because friction and drag immediately begin robbing the car of energy. At the top of the first hill, a car's energy is almost entirely gravitational potential energy (because its velocity is zero or almost zero).
The purpose of the coaster's initial ascent is to build up a sort of reservoir of potential energy. The concept of potential energy, often referred to as energy of position, is very simple: As the coaster gets higher in the air, gravity can pull it down a greater distance. You experience this phenomenon all the time.
Though roller coasters may seem scary, they are actually incredibly safe — modern coasters are designed so that millions of people can ride each year without any risk of injury.
The front seat offers the best view, of course and you get to see what's happening before the rest of your fellow riders do. You feel like you're leading the charge. Or go for the back seat because it offers more air time: your butt will hang in the air off your seat for much longer on those hills and drops.
Because of friction between the coaster cars and the track, along with air resistance as the cars move forward at high speed, the amount of mechanical energy available decreases throughout the ride. This is why the first hill must be always be tallest.
Different types of brakes are used to stop the train at the end of a ride. These brakes use friction to slow down and stop a roller coaster's momentum by converting the train's kinetic energy into heat energy. For example, roller coasters are kind of like riding your bike down a hill.
Basic mathematical subjects such as calculus help determine the height needed to allow the car to get up the next hill, the maximum speed, and the angles of ascent and descent. These calculations also help make sure that the roller coaster is safe. No doubt about it--math keeps you on track.
