Digital Dynamic Track System is equipped with optical sensors and 6 micro Smart Timers which allows 3 kinds of Newton's laws of motion quantitatively and accurately.
- The cart in this BA-219 Digital Dynamic Track System is the only cart that does the uniform motion meaning it moves at a constant speed due to its unique design of the cart.The cart of any other system in the market can not make the uniform motion due to the friction
- BA-219 Digital Dynamic Track System does provide the most accurate data quantitatively as to the third of Newton's laws of motio that forces always occur in pairs. (A force results from the interaction of two objects, and every force ('action') on one object is accompanied by a 'reaction' on another, of equal magnitude but opposite direction.)
- A level on the cart helps the dynamic track to be thoroughly balanced.
