In physics, a rigid body, also known as a rigid object, [2] is a solid body in which deformation is zero or negligible. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it.
ordinary solid object is approximately a rigid body, although the particles actually oscillate in thermal motion about their equilibrium positions, and they can be displaced slightly from those positions by external forces.
A rigid body has 6 configuration degrees of freedom because its most general configuration can be obtained by translating (3 degrees of freedom) and rotating (3 degrees of freedom) its initial configuration. A mathy way of saying this is that its configuration manifold is $\mathbb R^3\times \mathrm{SO}(3)$.
A rigid body is an idealization of a solid body where the deformations occurring on the body are neglected. In other words, the distance between any two given points of a rigid body remains constant regardless of the external force acting upon it.

A rigid body is an idealized solid object where the distance between any two points within it remains constant, no matter what external forces or torques are applied. This means that the body does not deform or bend—it stays the same shape.
May 19, 2023 · In physics, a rigid body (also known as a rigid object) is a solid body in which deformation is zero or so small it can be neglected. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it.

• In 3D, a rigid body has 6 degrees of freedom—three translation and three rotation. Guess what, vector equations of the type above would give us 6 scalar equations—just what we need. Here’s the great part: we can indeed generalize Equations 1 and 2. Let’s recap where we ended up for rigid bodies.
