Presentation transcript:

Hooke’s Law Post Lab Questions What is the relationship of the force on the spring and stretch of the spring? How do you think your results would change if you raised the softness of the spring? How would your results change if you decreased the amount friction? Using your response to the previous two questions, do you think the value of your spring constant would change? Why or why not?
