The Ball Traveler set is composed of the operating device in front of us and the ball trajectory behind us, the lifting system, the ejection system, the centrifugal force ejection system, the ball retrieval system and other systems. The set shows us the entire movement of the ball. In the process of these movements, the ball such as linear motion, circular motion, inclined motion, parabolic motion to show a variety of forms of movement. And in this process there will be energy conversion, such as we rotate the handwheel in the first level, through the lifting device will be lifted to the highest point of the ball, it has the gravitational potential energy in the process of falling will be converted into kinetic energy, which can be used to increase the speed of the ball. Through the multi-player collaboration of the whole set, we can not only experience the joy of this exhibit, but also recognize and understand the laws of motion, as well as our understanding of the problem of energy conversion.
