"Repulsion" refers to a strong feeling of disgust or aversion towards something or someone. In the context of the 1965 psychological horror film directed by Roman Polanski, it reflects the protagonist's intense fear and psychological breakdown. The film explores themes of isolation, mental illness, and the impact of trauma, showcasing how the main character, Carol, becomes increasingly repulsed by her surroundings and interactions, leading to disturbing hallucinations and violent behavior.

In physics, repulsion refers to the force that pushes two objects with similar properties away from each other. This phenomenon is most commonly observed in the context of electric charges and magnetic poles. For example, like charges (positive-positive or negative-negative) repel each other due to the electromagnetic force, as do like magnetic poles (north-north or south-south). Repulsion is a fundamental principle that governs interactions between particles and plays a crucial role in various physical systems, from atomic structures to macroscopic objects.

In the movie "Repulsion," directed by Roman Polanski, the protagonist, Carol, experiences intense psychological repulsion, particularly towards men and sexual advances. An example of this repulsion is when she becomes increasingly disturbed by the advances of her neighbor and the intrusive behavior of men, which leads to her mental deterioration. The film uses visual and auditory elements to amplify her sense of fear and isolation, illustrating how her repulsion manifests in violent hallucinations and ultimately contributes to her descent into madness.

In chemistry, repulsion refers to the force that causes particles with like charges or similar magnetic poles to push away from each other. This phenomenon occurs due to the electrostatic force between charged particles; for example, two positively charged ions repel each other. In molecular terms, repulsion can also occur between electron clouds in atoms, influencing molecular geometry and bonding. Understanding repulsion is crucial in explaining chemical reactions, molecular structures, and the behavior of substances at the atomic level.
