Answer:
Explanation:
When we sit on a sofa, the force exerted by the body weight compresses the spring and changes its shape. This proves that force exerted from outside can change the shape of an object. Another example of force changing shape is balloon filled with air. It changes its shape as air exerts pressure to its walls.
