Energy Transformation Involved with Roller Coasters

Much of the physics behind how roller coasters work is the energy transformation. Every loop, hill, twist, and turn depends on the type and amount of energy involved. There are two main types of energy involved: kinetic and potential. Different features of roller coasters use different amounts of kinetic and potential energy, which are what make the coaster go. Below is a table to better explain these types of energy:

Equation of energy
Ug = mgh
K=½mv²

When energy is high
at the top of a hill; chain
at the bottom of a hill

When energy is low   
at the bottom of a hill
at the top of a hill
Why energy is important
increases force of gravity
