Question

Define a rigid body and non rigid body.State the force applied on rigid and non rigid body.

Answer 1

In physics, a rigid body 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 exerted on it. A rigid body is usually considered as a continuous distribution of mass.

Non rigid body is a substance which can be compressed and manipulated.

effect of force on rigid body - changes the state of rest or of motion of the body

effect of force on non rigid body - changes the shape and size of the body and also changes the shape and size of the body
