Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific discipline?Physics and Materials Science
2. What is elasticity in physics?Elasticity is the ability of a solid to resist being changed by a force and to go back to its original shape when the force is removed.
3. How does a rubber band stretch and then return?In rubber, long chains of molecules uncoil when stretched. When the force is gone, the chains coil back, making the rubber band return to its original shape.

Elasticity: The property of a material that allows it to return to its original shape after being deformed by an external force.
Deformation: The change in the geometric form or size of an object under the action of applied forces.
Hooke's Law: A principle stating that the strain in a solid is proportional to the applied stress within the elastic limit.
Elastic Modulus: A quantitative measure of a material's stiffness, representing the ratio of stress to strain.
