Question

When a spring is stretched, the force changes the _________ (mass/shape) of the spring.

Answer 1

1. A force that increases the length of a body is called tensile force.
2. A tensile force must be applied to the spring to stretch it.
3. When a spring is stretched, the distance of separation between the atoms of the spring increases.
4. Due to the change in the distance of separation between the atoms of the spring, it undergoes a change in its shape.

Hence, when a spring is stretched, the force changes the shape of the spring.
