Poor Physics #2


Lee and Carter parachute down Eiffel Tower 

In order to escape from their pursuers, Lee and Carter take a French flag and use it as a parachute to come down from the tower. However, their pursuers shoot at the flag, creating numerous holes in it. This causes them to fall quicker. Because of the “wind”, Carter and Lee are pushed forward and they land in the fountain safely.


When we look at the motion of the parachute falling by itself, it makes sense since the “wind” creates lift and pushes them safely down the tower. However, as they are landing, a fountain that is shooting up water is present. Notice how the water falls down nearly straight down. If the “wind” was blowing Carter and Lee at the speed it was supposed to be, the fountain water would be falling down at an angle due to the same force from the “wind”. But, there is no evidence based on the fountain that there is such wind that could push two people down in a parachute. The parachute and the fountain both have to be affected by the external force, the wind. In the movie, the parachute is gliding due to lift, stating that there is an external force, while the fountain is not affected by anything, contradicting to what the parachute is showing. Therefore, two things do not match, making it a scene with poor physics.
