PHYSICS IN MOVIE (KUNG FU HUSTLE)

      Kung Fu Hustle is a 2004 Hong Kong-Chinese martial arts action comedy film, directed, co-produced and co-written by Stephen Chow, who also stars in the lead role. The story started in 1940's China, and gangs rule the city. The most notorious of them all is the axe gang, lead by the insane Brother Sum. A slum called Pig Sty Alley is the only area safe from the Axes because the people there are so poor. Soon, wanna be gangster Sing and his pal Bone attempt to extort money out of a barber and fail, drawing the real Axe Gang to Pig Sty. However, it turns out that there are several kung fu masters living in the slum, and soon the two sides are enemies. 

      This movie is all about kung fu played by gangster chinese to protect themselves from anermies. The term Kung Fu refers to the martial arts of China. The physics concept in this movie is about the sound waves. Some of the men can use the musical instrument to produce sound waves that are strong enough to damage things and and make anythings into half. The theory is that when a sound with certain frequency hits an object at which the objects molecules natural vibration is at the same frequency of the sound that hit it then a resonance occur and a violent huge wave of vibration is created and this energy is taken by the molecules of the object and due to uneven vibration within the object causes the object breaks. For example, a singer who creates the sound that vibrates with the same frequency of the glass molecule and thus resonance occur and breaks the glass. Besides that, we also can see the application of the newton's third law in which there is action-reaction when they hit people by kung fu.
