Question
Please help.
Students are asked to create the graph of the skateboarder situation as you were asked to do. A student creates the graph shown in Figure 1. The student explains that the graph shows how the skateboarder first "goes down", then travels across the bottom of the half-pipe, then goes "back up", etc. Discuss how the student might be thinking as they create such a graph. What aspects of the situation might the student NOT be thinking about? What would you first say to or ask this student to help them to think differently about the situation? Why?Explanation / Answer
From the given question,
The studen might be thinking that skaterboard is going with constant velocity.
As the skaterboard goes downwards in slope it accelerates. so the slope should be curve.
similarly, when it travels up, it decelerates. so the slope should be curve.
we would suggest that in sloping situations, the body has a component of gravity ( unless air resistance balances it after some time), so the dispalcement time graph cannot be straight line in upward or downward slope.
