Question

why does a body regain its shape & size when deforming force are removed? explain it on the basis of atomic view of matter.​

Answer 1

A body regain its shape & size when deforming forces are removed because atoms and molecules get back to their equilibrium positions

Explanation:

• We know that solid bodies have a definite shape and volume. This is because molecules and atoms are packed in specific positions at certain intermolecular distances.

• When deforming forces are applied, the atoms move from their original position which causes the deformation in the shape.

• When this force is removed, atoms move back to their original position.

• This property of solid bodies is called elasticity
