A lot of people look at roller coasters as an exciting example of physics, like potential energy versus kinetic energy or inertia, and rightly so. [Jared] looks at them and wonders about the controls.

Roller coasters rely on gravity to take them to the end of the track. This involves two types of energy, potential energy and kinetic energy. Potential energy is the energy an object has because ...

The restraint features over 40 rides, most of which rely on human and kinetic power to run. The biggest of which, Penolo is a rolling gravity-powered roller coaster that can reach speeds of over ...
