Main Document

Newton's Mountain JS Model 

written by Todd Timberlake and Mario Belloni

The EJS Newton's Mountain JS model illustrates the motion of a projectile launched from the top of a VERY tall mountain on Earth. The diagram shown in the simulation is taken from Newton's A Treatise on the System of the World, which he wrote after the Principia, but the basic idea is found in the Principia itself. Newton concluded that a projectile launched horizontally with sufficient speed would orbit Earth rather than crashing to Earth's surface. Thus the motion of a projectile fired on Earth was not qualitatively different from that of the moon orbiting Earth.  

EJS Newton's Mountain JS Model was created using the Easy Java Simulations (EJS) modeling tool.
