Study Notes
Tension in Physics
- Tension is a force that is transmitted through a rope, string, or wire when it is stretched or pulled tight.
- At the atomic level, tension arises from the electromagnetic interactions between atoms or molecules, causing them to attract or repel each other.
Measuring Tension
- Tension is measured in the International System of Units (SI) in units of newtons (N) or sometimes in pounds (lb) or kilogram-force (kgf).
Opposite of Tension
- The opposite of tension is compression, where a force is applied to an object to compress or shorten it.
Transmission of Tension
- When an object transmits tension, its ends are pulled apart, exerting an equal and opposite force on the objects attached to each end.
