distance between 0 and P2 would be the distance between expectation and concentration, the momentum of the
mind's motion if P2 approached 0 means a harmonious balance between expectation and concentration, which
makes the team feel comfortable. Meanwhile, the gap between P2 and 0 of the strong team is smaller than the
weak team, which means that the differences between objective and subjective momentum are minor, and the
pulling force of the game and mind is small so that the player can feel more comfortable.

4. Discussion and Conclusion
This study had collected data on NBA rules change throughout the recent decade. The NBA rules have
developed, updated, and explored constantly; after these years, the current rules make the GR value closer and
closer to the most reasonable zone 0.07-0.08, and the AD value is getting closer and closer to the level of 0.045-
0.06. With physics in mind, it can be observed that the v and m both approached 1/2 and momentum P1
approached 1/4, the rules of the NBA keep the game is fairer and fairer after these decades. The NBA game's
force is around 0.003, which gets close to a reasonable zone for basketball, making players feel exciting and
attractive and attract players most reasonably. Moreover, it is the best time to finish the game; if longer, the
force will be smaller and cannot attract players.
Moreover, the Ep of NBA is located around 1/4 to make the expectation of NBA more specific, and the
momentum of mind's motion (P2) stabilized around 0 after getting higher, it meant that the momentum of mind's
motion is getting higher, and NBA is fascinating, and players have risk rate to take the engagement.
Furthermore, this study considered the physics in the mind of different level players from the game's side; it
can be observed that a strong team reached the v = 1/2 in a short time while re keep the velocity. However, the
weak team needs to spend a longer time to reach the velocity and has a lower ability to keep the velocity, and
the velocity of the weak team is a little lower than v = 1/2.
While both teams' forces are 0.004, the strong team has a higher force in mind during the game's initial
process, which means the strong team had better adhesion. The energy conservation of different teams was
proposed to analyze the momentum of the mind and game, where the strong team reached the P1 = 1/4 and Ep
=1/4 in a short time. Thus, the strong team can reach his expectation and concentration quickly. Moreover, the
velocity and momentum, the potential energy of a strong team are higher than the weak team, which means the
ability and concentration, the expectation of a strong team are higher than the weak team. Meanwhile, the P2 of
a strong team is higher than the weak team, the strong team has a higher magnitude of engagement, and the
process of a strong team is fascinating. Also, the distance between P2 and 0 is associated with a sense of balance,
making the strong team felt more comfortable because the distance is smaller than the weak team.
Game refinement theory and motions in mind concept can commonly be used to measure and analyze the
sophistication of game from the overall game side. Also, for the dynamical game process, we can analyze the
details of each team or each player, from objective sides and subjective sides, to know how instantaneous
feelings during the game process based on different game results such as scores.
