A body is said to be a rigid body if the body remains in its original shape even under the influence of external force. We can also say that if distance between two points of the body does not change with time regardless of external forces exerted on it, then the body is said to be a rigid body.

Rigid body is due to the presence of forces of attraction between the atoms or molecules and so they are tightly packed. Thus there positions are fixed. If the position is not fixed then it will not be a rigid body as the molecules will move , so because of this the state of the body will change.

Definition of a Rigid Body:
A rigid body is an object in which the distance between all pairs of particles remains fixed.
Explanation:
- A rigid body is a type of object where the relative positions of its particles do not change.
- This means that the distance between any two particles in the body remains constant, regardless of any external forces acting on it.
- In simpler terms, a rigid body does not deform or change shape when subjected to forces or movements.
Example:
- A solid metal bar is a good example of a rigid body. When you apply a force to one end of the bar, the other end moves in unison without any change in the shape or size of the bar.
Characteristics of a Rigid Body:
- The shape and size of a rigid body remain constant.
- The distance between any two particles in the body does not change.
- The particles of a rigid body move together as a single unit.
Importance of Rigid Bodies in Physics:
- Rigid bodies are essential in physics for simplifying the analysis of complex systems.
- They allow for the application of principles like conservation of energy and momentum in a more straightforward manner.
Conclusion:
In conclusion, a rigid body is defined as an object in which the distance between all pairs of particles remains fixed. This characteristic distinguishes rigid bodies from deformable objects and is crucial for understanding the behavior of physical systems.
