Quick comprehension check
“Describe a scenario where a contact force causes a visible change in the structure of an object. Explain which object applies the force, which object experiences the force, and how the structure changes. Explain how the contact force between a hammer and a nail changes the structure of the wood the nail is being hammered into. ”
