2019 #3 Free Response Question - AP Physics 1 - Exam Solution

The video tutorial covers question #3 from the 2019 AP Physics exam, focusing on a projectile launcher with a spring. It discusses the hypothesis that the spring constant remains the same for different compression distances. The tutorial guides through designing an experiment using conservation of mechanical energy, measuring launch speed, and analyzing data to confirm the hypothesis. It also explores the relationship between mass and launch speed, emphasizing the importance of reading ahead in problems and reducing experimental uncertainty.

Explain how conservation of mechanical energy applies to the experimental design.

What is the significance of the equilibrium position in the context of the experiment?

Discuss the importance of measuring the initial displacement of the spring in the experiment.

Sketch a graph of launch speed as a function of sphere mass based on the experimental setup.
