Thiago on the Moon
Keywords:
Sports, Physics, Mechanics, Gravity, Football, Thiago AlcantaraAbstract
In the world of football, there is a retired footballer called Thiago Alcântara. A feat that many football fans around the world would remember him by is his goal against Porto in the second leg of a Champions League quarter-final match in 2021 [1]. This paper investigates the metrics of this shot on Earth and then proceeds to investigate whether the shot would have entered the goal if it were taken on the Moon by presenting it as a simplified projectile model. The calculations show that on the Moon the shot would have travelled approximately 3.76 m above the crossbar.
