Solid matter is composed of a large number of atoms or molecules, and these particles are either electrically charged, or electrically neutral as a whole, but the positive and negative charge centers do not coincide, or magnetic fields are generated due to the movement of charges, so that an electromagnetic force is generated on adjacent atoms or molecules, which prevents adjacent particles from getting too close or too far away. Therefore, for the whole solid, the compactness among the internal particles can maintain a certain relative position, which is reflected as rigidity in the macro, and the force generating rigidity is called rigid force.
- Chinese name

- Interpretation
- The force that produces rigidity
Because the distance between molecules of liquid and gas is larger than that of solid, and the interaction force between molecules is weaker than that of electromagnetic force, liquid and gas almost do not reflect rigidity. planet In the process of rotation, from the inertial reference system, the combined force of gravity and rigid body force generated by the planet itself provides the centripetal force of its surface and internal matter; from Non inertial reference system Look, the rigid force is used to counteract the squeezing or tearing of gravity and centrifugal force on the planet itself, so as to keep the planet spherical.
