Contact Forces Spring Scale
📚 Part 1: Understanding Contact Forces
1. What are contact forces? Explain in your own words and give two examples from everyday life.
2. How does a spring scale work to measure force? Describe the basic mechanism.
3. When you apply force to a popsicle stick using a spring scale, what type of contact force are you creating? Explain your answer.
4. Describe what happens to the popsicle stick as you gradually increase the force applied by the spring scale. Be specific about the deformation you observe.
5. Explain how the spring scale's mechanism allows it to accurately measure the force being applied to the popsicle stick. What physical principles are involved?
