 +You can get velocity data by derivative position data.{{ hh_mocap:capture11.png?65 |}} Using this equation, you can get velocity data of x,y,z. This is time dependent acceleration.
 +
 +Once you get the x,y,z velocity data,
 +
 +v = โˆš((xi)^2) + ((yi)^2) + ((zi)^2)
 +
 +exploit this equation to get velocity of rigid body.
