Their participation in such an environment allows investigation of principles which are known but not truly understood. The use of environments conforming to this model may help re-enforce existing knowledge, and allow exploration of the physical system. Game based environments are less academically orientated, their purpose is to introduce principles and concepts to the users, rather than to provide any quantitative development of the user's physical knowledge. As for the development of the experiments this is not made any easier by the categorisation of the types. Kinematic experiments are the simplest.
Mathematics strongly supports calculations involving the interaction of force and energy.
Such systems may be easily represented by solid objects experiencing a controlled motion. While there are many different applications of forces, and much may be gained from VE's ability to transpose the frame of reference of the observer to one relevant to the solution of the physical system, Kinematics is but one small field in physics. In addition, there are only so many experiments which may be created on one subject. Providing new and original experiments in this field is not easy. Meeting the two requirements above makes this task more difficult.
