Contact Forces
Grade 7•45 minutes•1.A Develop a model to describe interactions between two objects as they collide and show the changes that occur in the structure of both objects when one object is damaged as a result and also when neither object is damaged as a result. 1.B Ask questions that arise from observations of collisions between two objects in order to seek additional information about factors (causes) that might affect the outcome of such collisions.
Learning Objective
I can explain how contact forces can change the structure of colliding objects.
Practice Questions

1. Define "contact force" in your own words and provide two original examples (different from those in the video).
2. Explain how a contact force can change the shape of an object. Give a specific example.
3. Imagine two cars colliding. Describe how the contact force between the cars could change the structure of each vehicle. Consider scenarios where one car is more damaged than the other.
