This instrument is a mechanics experiment instrument for senior high schools, designed to study laws of motion, and record movement time-space information, upgrading many ＂qualitative＂ experiments into ＂qualitative＂ ones. It applies to the following experiments in middle school education:

a.       Study the motion of horizontal cast objects;

b.      Study that of slant cast objects;

c.       Verify the law of conservation of mechanical energy;

d.      Complete non-elastic collision;

e.      Complete elastic collision;

f.        Verify the centripetal force formula;

g.       Study simple harmonic (pendulum) rules;

h.      Simple harmonic vibration images;

i.         Free-fallers motion.
