This is a simulation for three particles with different initial velocity (vy_1=v, vy_2=0,vy3=-v) under the same gravity g=10m/s^2

You can drag the initial position of particles as well as initial velovity (drag the tip of velocity arrow--red )

The number of frames per second can be adjust with slider. (initial value is fps=5, fps=200 is real time case)
