Particles are point-based objects with no dimensions or orientation, used to simulate small particles in a system. Rigid bodies are solid objects with dimensions and orientation that interact with other objects in a physics simulation. Rigid bodies have mass, volume, and inertia, while particles are massless and do not have volume or shape.
An elastic body can deform under stress but will return to its original shape when the stress is removed, while a rigid body does not deform at all. In other words, an elastic body can store and release energy in the form of deformation, while a rigid body cannot.
In physics, a particle is a point-like object that represents a small portion of matter with no spatial extension. A body, on the other hand, refers to an object that has physical dimensions and occupies space. Essentially, a body is made up of particles, but it has a defined shape and size whereas a particle does not.
Rigid bodies do not deform when subjected to external forces, maintaining their shape and size, while deformable bodies undergo changes in shape and size when subjected to external forces, such as stretching or compressing. Rigid bodies are commonly used in mechanics for simplifying analysis, whereas deformable bodies are important in studying materials' properties and structural elements.
The instantaneous center of rotation is a point in a rigid body that has zero velocity at a specific moment in time. It is the point around which all parts of the rigid body have rotation at that moment. It helps to analyze the motion of the rigid body at that instant.
The degree of freedom of a rigid body when one point of the body is fixed is zero. This means that the rigid body has no motion at all as it is completely pinned down by the fixed point. Any movement of the rigid body would cause it to become non-rigid.The degrees of freedom of a rigid body are expressed in terms of six independent parameters which are:Translation in three orthogonal directionsRotation around three orthogonal axesWhen one point of the rigid body is fixed the body cannot move in any of these directions resulting in a degree of freedom of zero.
The key difference between a particle and a rigid body is that a particle can undergo only translational motion whereas a rigid body can undergo both translational and rotational motion
In statics a particle and a rigid body are viewed as pretty much the same thing, and can be analysed with the same methods. Assuming that a particle is in equilibrium i.e. the sum of the forces and the moments are all zero, and that a rigid body is made up of particles, we know that if each particle of this body is in equilibrium (internal forces cancel each other out) then we can conclude that the body must therefore also be in equilibrium. The difference between these a particle and a body is we will usually find a particle in space without these so-called constraints, while a rigid body- a beam comes immediately to mind, is usually constrained in some or other manner, by either a pin or roller or any other way.
An elastic body can deform under stress but will return to its original shape when the stress is removed, while a rigid body does not deform at all. In other words, an elastic body can store and release energy in the form of deformation, while a rigid body cannot.
The relative position of the points on any object will not change at any application of force then,it is called rigid body.OR,It is defined as a system of particle,which does not deform.....,

In classical physics, a rigid body is an idealization where the distance between any two points on the body remains constant. However, in reality, all physical bodies have some degree of flexibility or deformation under certain conditions. Therefore, there is no truly rigid body in practice.
It has a rigid skeleton but the body is flexible.
Rigid bodies do not deform when subjected to external forces, maintaining their shape and size, while deformable bodies undergo changes in shape and size when subjected to external forces, such as stretching or compressing. Rigid bodies are commonly used in mechanics for simplifying analysis, whereas deformable bodies are important in studying materials' properties and structural elements.
A rigid rotor is a 3-dimensional rigid body, such as a top -a children's toy. To describe the orientation of a 3-dimensional object with respect to a 3-dimensional coordinate system three angles are required. If the angles do not vary in time, the rigid body is standing still; when the angles vary in time the rigid body is rotating and is referred to as a rigid rotor (also known as rigid rotator).A special rigid rotor is the linear rotor which is a 2-dimensional object (a pencil), requiring two angles to describe its orientation. Sometimes one considers rotation of a single particle around an axis fixed in space, then one angle is sufficient to describes the system fully.
A rigid body does not deform under stress, maintaining its shape, while an elastic body can deform under stress but will return to its original shape once the stress is removed. Rigid bodies are idealized as having infinite stiffness, while elastic bodies have finite stiffness allowing for deformation.
There is no difference
The difference is that you can not apply perfume to your body,if you do it ,it would be harmful for skin and in contrast body spray can be apply directly to body.
