Rigid bodies
Definition
Rigid bodies are objects that do not deform under applied forces; their shape remains constant even when subjected to external forces or torques.
Analogy
Picture a solid metal rod. When you push or pull on it, the rod does not bend or change shape. It remains rigid and maintains its original form.
