Gravity is a program to simulate the path of move for bodies (i.e. objects with mass) altered by the gravity drive between each other, i.e. a gravity simulator. Gravity is proposed to schools, teachers, students, undergraduates in physics and anyone interested in natural sciences, physics or to those just like spectacular programs. Limited to 10 seconds simulation. No export, import, warn, and log.
