- Scientific meaning: Measure of the tendency of a force to cause rotation about a point; calculated as force times the distance from the pivot point.
- Everyday meaning: A short period of time or a specific point in time.
Pressure
- Scientific meaning: Force applied per unit area, indicating how concentrated a force is on a surface.
- Everyday meaning: The feeling of being pushed or squeezed by surrounding people or things; stress.
