Question

Quizplus · Accepted Answer

The scene is a fantasy because it likely violates the conservation of momentum and energy. In real life, the forces and reactions involved in such a scenario would not allow for the exaggerated effects seen in movies without violating these fundamental physical laws. Conservation of momentum ensures that the total momentum before and after a collision remains constant in an isolated system, and conservation of energy dictates that energy cannot be created or destroyed, only transformed. The exaggerated effects seen in movies often do not account for these principles accurately.
