Elástico

The video explains how elastic materials regain their original shape after an external force is removed, while non-elastic materials remain deformed. It also highlights that the deformation in elastic materials is proportional to the force applied.

What happens to a material when an external force is removed?

• It melts.

• It becomes heavier.

• It regains its original shape.

• It changes color.

How do elastic materials respond to deformation?

• They remain deformed.

• They change temperature.

• They break apart.

• They regain their original shape.

What is a key difference between elastic and non-elastic materials?

• Elastic materials are always heavier.

• Non-elastic materials regain their shape.

• Elastic materials regain their shape, non-elastic do not.

• Non-elastic materials are always transparent.

Which of the following statements is true about non-elastic materials?

• They are unaffected by external forces.

• They become elastic over time.

• They remain deformed after the force is removed.

• They regain their original shape after deformation.

What is the relationship between force and deformation in elastic materials?

• Deformation is proportional to force.

• Deformation is inversely proportional to force.

• Deformation is unrelated to force.

• Deformation decreases as force increases.
