Lab: Energy Skate Park
Objectives: Upon the completion of this lab the student will be able to:
Read and comprehend (at least on a basic level) an advanced scientific research paper
Evaluate original research in terms of the Scientific Method
Showcase an understanding of the Scientific Method
Summarize the research conducted by a scientist in simple terms
Purpose You are investigating the relationship between kinetic energy, potential energy, and total energy when only conservative forces are present and then again when non-conservative forces are present. The data will be analyzed graphically in order to provide a clear trend.
Directions
Part 1- Conservative Forces
1.
Open Energy Skate Park
. Choose Intro
. 2.
Take time to play around with the simulation. Make sure all boxes are checked.
What do you notice about the total energy, kinetic energy, and potential energy in the bar graph? The total energy remains constant then divided with potential and kinetic energy
What do you notice about the pie graph? What must you do in order to get the pie graph to be larger? In order to get the pie chart to be full you would either need to be at the highest point in the skate park or the lowest point

We also need to establish numbers for mass and speed. 4.
Choose “Slow Motion.” Place the 20-kg skater at 6-m and start the timer when you hit play. Pause both
timer and sim when the skater is at 4-m, 2-m, 0-m, and 6-m. Record the height, speed, and time in the table below. Continue recording until you’ve reached 30-s. 0-m/s

6.
Copy this data table into the supplied Excel spreadsheet. Copy and paste the graph below.
Ill be frank im not sure what happened? I was using the formula correctly but I kept getting fluctuating total energy
7.
How does kinetic energy change with time? Potential Energy? Total Energy?
As an object's motion accelerates, it undergoes a transition from potential energy to kinetic energy. The amount of kinetic energy remains constant until the object either decelerates or accelerates further.

8.
How are the potential energy and kinetic energy related? Is this visible on the graph, and how?
The energy transformation goes back and forth between potential and kinetic energy. You can see this on the graph because they always move in opposite directions, showing how they're connected.
