Answer 1

1. **What is the unbalanced force?**
The unbalanced force is the sudden stop of the skateboard when the wheel hits the rock. This force causes the skateboard to stop moving while Terry continues to move forward due to her momentum.

2. **How does inertia affect Terry and her skateboard?**
Inertia is the tendency of objects to keep doing what they are already doing. Because Terry's skateboard stopped suddenly, Terry kept moving forward because of inertia. She almost fell but was able to catch her balance at the last moment.
