Q1: What are two examples of materials that can be bent without breaking?

[Answer]

Some materials can be pulled or bent into a new shape. For example, you can bend a piece of wire into a new shape and it will stay the way you've bent it.

Materials that will bend or stretch without breaking are called flexible materials. But because they do not go back to their starting shape they are not elastic.

Cloth and rope are flexible, as is aluminium foil used to wrap food.
