This simulation demonstrates the Conservation of Mechanical Energy. At the top of the initial hill, the coaster possesses maximum Potential Energy (PE).
As it drops, gravity converts this potential energy into Kinetic Energy (KE), increasing its speed. In an ideal frictionless system, the Total Energy ($TE = PE + KE$) remains constant throughout the ride.
PE = mghKE = ½mv²TE = PE + KEWhy does the coaster fail?
If the initial height is too low, the coaster won't convert enough PE into KE to survive the loop. It requires a critical minimum speed at the top of the loop to counteract gravity and stay on the track (Centripetal Force).
