Suspense and Shock

Imagine a scene in a classroom with students and a teacher. The camera reveals that there is a bomb under the table to the audience but however in the diegetic world (the students and the teacher) are aware of it. Will we be saved? Will the bomb go off? This is SUSPENSE. 

An example of suspense is in the film, Sabotage (made by Alfred Hitchcock). In this film, a boy has been given packages to deliver (by a terrorist) which us, the audience know that inside is a bomb that is due to go off at 1:45pm, however the boy is unaware of this fact. The tension builds as the time comes closer and closer, near the end Hitchcock adds more tension by repeating a certain imagery which is of clocks; while we are seeing this imagery the sound is parallel as it is of a ticking sound. This warns the audience that the time is near the end which has brought the suspense to it's climax.

Imagine the same scene except that instead of the camera revealing the bomb under the table, it simply just explodes without any warning, killing everyone which is present. This is SHOCK.

An example of shock is the film Children of Men. In part of this film the audience see a man go into a coffee shop, which is crowed with people watching the news that is reporting the death of the youngest person alive, the news seems abnormal and almost a trick to get a large number of people in one place. After the man leaves the shop a few minutes later the shop explodes, with a dark gust of smoke coming from the shop
