Question
State the effects of a force applied on
- A non-rigid, and
- A rigid body.
How does the effect of the force differ in the two cases?
Solution
A force when applied on a non-rigid body changes the inter-spacing between its constituent particles and therefore causes a change in its dimensions and can also produce motion in it.
On the other hand, a force when applied on a rigid body, does not change the inter-spacing between its constituent particles and therefore it does not change the dimensions of the body but causes motion in it.
