Definition
Noun: - The force by which bodies repel one another: A physical interaction that causes objects to push away from each other. This is the opposite of an attractive force.
Usage
- This term is primarily used in the context of physics to describe a fundamental interaction, such as the repulsion between like magnetic poles (north-north or south-south) or between electric charges of the same sign (positive-positive or negative-negative).
- It describes a measurable push that increases as the objects get closer.
Examples
- Noun:
- The repulsive force between the two positively charged protons is immense.
- Magnets demonstrate a clear repulsive force when you try to push the same poles together.
Advanced Usage
- "To overcome a repulsive force": To apply enough energy to push objects together despite their natural tendency to repel each other.
- Nuclear fusion requires overcoming the powerful repulsive force between atomic nuclei.
