Magnus force model applied research in table tennis flying process trajectory

Mengjie Qiao

Table tennis movement process is very complicated; it includes space movement and its own rotational movement. In table tennis self-rotating movement, it has non -rotating and rotating two forms; table tennis space movement trajectory is correlated to racket and table tennis collisionmoment friction force, push force as well as momentum and others, and it can be divided into horizontal movement trajectory and vertical movement trajectory. Table tennis in flying process mainly suffers vertical and downwards gravity, vertical and upwards buoyancy force, air resistance that in the opposite direction ofmovement, aswell as self-rotating produced Magnus force, its movement trajectory is arc. The paper puts emphasis discussion on table tennis flying process self-rotating produce Magnus force that is table tennis running processÂ’s every kind of force status; finally it defines table tennis first trajectory equation by force analysis.
