Discussion Questions for Graph 1
- How high is the model skier at the beginning of the trajectory? At the end?
- What is the length of the slope? Draw a model of the slope.
- What is the velocity of the skier at the end of the trajectory?
- Approximately how much mass does the model (skier plus skis) contain? Is it possible to obtain a precise estimate?
- Is it possible to estimate the size of the skis? How large might the skis be?
Discussion Questions for Graph 2
- Describe the motion of the skier.
- Is this slope different than the slope from the first graph? If so, how?
- Describe the forces on the skier. How do the forces affect the motion?
Discussion Questions for Graphs 3 & 4
- One of these graphs shows the front view of the turn, and one shows the side view. Which graph corresponds to each view?
- Compare these two graphs to Graphs 1 and 2. What are the main differences?
- Why are these graphs not smooth? What happens to the skier in the region of irregularity?
- What is the effect of the curve on the skier’s motion?
