Force
A force is applied in i) a non- rigid body and ii) a rigid body. How does the effect of the force differ in the above two cases?
A force when applied on a rigid object does not change the inter-spacing between its constituent particles and therefore it does not change the dimensions of the object, but causes motion in it.
On the other hand, a force when applied on a non-rigid object, change the inter-spacing between its constituent’s particles and therefore cause a change in its dimensions.
